In a convoluted sense, vampires really don't dream too much, the Draconian, Unstet, and the Nosferatu Class are peak among these.
The Nosferatu classifications are grotesque vampires, mutated horribly by a disease dubbed Polymorphic Hemophilia. They become extremely sensitive to light and will combust with prolonged exposure. Common disfigurements include a more pointed set of ears, teeth serrations, a flattened and upturned nose, elongated canines, fingernails which harden beyond what would be normal for humans, and finally their skeletal structure begins to show through their bodies as they emaciate. Because of their sensitivity to sunlight, the Nosferatu must sleep during the day, and by nature will go to ground when they must sleep. Their bodies are almost like a mummified corpse should it be stumbled upon whilst one dug a hole. The best method for disposal is to stake the heart and burn it, scattering the ashes at a crossroads. Another method is to fully expose the sleeping corpse to full sunlight.
The Draconians are most amongst the highest category of vampire as far as mysticism and danger level goes. They share a likeness with the Nosferatu in their sleeping habits. Only when these vampires become elder or more powerful are they capable of daytime activity. It has been known for the vampires they sire to inherit a portion of their strength; some fledglings are born with only minor solar sensitivities. The transformation process for this particular breed of vampire takes place when they consume the blood of a virgin of the opposite sex. Members of the same sex or non-virgins will be changed into what are known as ghouls, which become slaves to their vampire sire's will. Draconians are dangerous not only for their natural instincts of violence and need for human blood, but also in their physical appearance. They look just as a man or a woman might look on a cold day. Another dreadful fact about these creatures are the other worldly powers they posses, from the ability to become as shadows to walking on walls, most are capable of rapid healing or regeneration; telekinesis and pyrokenisis are also common abilities. They are highly susceptible to holy religious artifacts as well as weakened when crossing running water. The best method for hunting these particularly supernatural creatures is to follow it at night, when it beds for the day, wait for it's slumber then remove its head, stake the heart and destroy its sleeping box, scatter the dirt inside, burn the body and scatter the ashes at a crossroads.
Unstet classified vampires never sleep, therefore, they do not dream, they also are not burned by sunlight, the sign of the cross, or affected by the most common means of repealing or destroying of vampires. When exposed to sunlight, Unstet skin will reveal its true nature, the diamond like structure of the flesh will reflect in the light. Thus Unstet avoid broad daylight and move about at night when cloud cover is not in good supply. Records indicate these vampires exist only in limited numbers as their method of conversion has a high mortality rate. Their means of transformation is through a secretion of their body known and titled only as venom. The venom is also highly acidic in that it will dissolve through most objects. The dangers of these vampires exist in their immediate superiority to the initial stages of development for most vampires. They are strong and remain strong, never decreasing or increasing in strength. The older the Unstet is, the wiser and more dangerous it becomes. Human confrontation is to be absolutely avoided in all possible causes with these creatures. The only conventional means of their destruction is through the use of fire boosted by modern accelerants such as Napalm, white phosphorus, magnesium phosphate, or any other high temperature burning chemicals. It should be noted the Unstet are highly potent and excessively violent when they are in the first year of their birth. The cause is unknown in modern human knowledge.
Another category of Vampire exists which is similar to the Draconians, these Vampires are believed to be held in a hierarchical society and a hive mind where they have a singular matriarch. These rumors have been so far left unconfirmed, not even the ancient Voulturi (whom oversee and act as the governing body of the Unstet) have been able to dig much up on this queen. Their secrets remain, for the most part, safe. For the sake of this document these particular vampires will be called Vita Sanguis as their particular method for transformation is an exchange of blood between the master and the fledgling. The Vita Sanguis are very similar to the Draconian class and can be mistaken for each the other. The primary difference between the two is the mysticism the Draconian wield; while the Vita Sanguis are unable to walk through walls or turn into mist, they are immune to the effects of holy relics and running water.
Mankind has been well aware of each of these creature and has been compiling resource material for centuries, with the advent of modern globalization information is spread and made more widely available than ever thought possible. With this ability to communicate so effectively the Vampire scourge of the planet has found it more and more difficult to keep their existence secret, but have found it to be just as easy to coordinate their own efforts in a global movement.
Therefore, I can confirm beyond a shadow of a doubt, Seras Victoria cannot dream.
Rather, she should not be able to dream, but her master and she herself have dreamed before.
He was coming for her, and she never felt weaker, she was helpless in this place, in her dreams. Her pursuer played this like it was a game of cat and mouse. He would only just reach her for her to get away. Seras tried everything in her power to pass through the wall or to fight the enemy with her other worldly powers, but it was useless. This was like in Cheddar, when she was mortal all those years ago, more than thirty. A screeching whine filled the air around her, her pursuer was already after her again, he had cut her arm off and she was still going, the blood which should have regrown the arm was only spilling. She rounded the corner and arrived at what was the main sitting room in Hellsing manor. Integra was already drinking her tea, Walter stood just behind the aged Lady Knight, a smile filled his face as wires shot out and tore Integra to bits, Integral's head rolled before Seras, as she looked down the head smiled arrogantly, "Come now Police Girl" it said.
The butler's micro filament wires wrapped around Sera's ankles and the aged, deceased butler begins pulling her in, closer and closer. His face twisting and turning, Seras scrambles to escape clawing away with her one arm and as she turns to face down her tormentor she finds Walter's elderly kind face was gone; it is replaced by a horribly disfigured countenance, scar tissue enveloping its whole face. He brings back his hand laughing manically, not unlike how her master does when on the killing field, she screams and lashes out at the monster.
Seras rousted herself from the ground, still half in terror. Her dream, it was so real, it terrified her to the core, she who had gone to hell and back with the failed Nazi Invasion of London in 1999. Her dream triggered a reflexive lash out while she screamed and phased through the floor, leaving a No Life King without his head. Her mastery of her abilities were complete, why did she dream in such a sad state? Her abilities have been tested again and again by Sir Integra, and she is every bit as capable as her master. When she was sent to dispatch that Lich twenty years ago she was not all that affronted by its grotesque habit of conjuring the dead and its taste for the frigid. The dream, it was so real, whenever she felt pain, it seared through her. Never, not since her dream with the Harkonnen, did she even dream.
When Seras came to her senses some seconds later, she popped up immediately through the floor, the hugest of apologies already on her lips, but she does not find her master there.
