Ford had never liked sleeping. He didn't like to admit it, just like he'd never really liked admitting his addiction to alcohol, even thought it was really rather obvious. He didn't like it because he liked to be in control. When you were asleep, you were surrendering your control to some darker part of your mind.
And so he especially didn't like dreaming. He would laugh at anyone who tried to tell him that dreams meant something, because he didn't like the idea that his subconcious knows more than he does, or that it would have the gall to try and point things out to him.
Unfortunately, in the middle of the night, he would sit quietly in a darkened room and slowly get more and more angry at his mortal needs. He ought to be out at a bar, but he's a bit tired to stand up at this point, and doesn't want to pass out in a crowded public place. And so he would sit there until he had no choice but to surrender to the embrace of dreaming, and he would sleep. Much as he hated to.
Still, in the morning, he would awaken, feeling like crap and wishing he had gone to bed earlier. He would get himself a drink and rush out to a bar to get even more drinks and he would forget all about it until the evening when the whole damned thing would repeat itself. Except, today, things happened differently. He woke up, feeling like crap and wishing he had gone to bed earlier, got himself a drink, let out a cry of frustration, and threw his drink at the wall, where it shattered. He let out a single sob, grabbed his towel, cleaned up his mess, got himself another drink, and stared at the wall for a few minutes. Then he got his faithful Guide, and opened it.
The Hitchhikers Guide To The Galaxy, which is, as I'm sure you all know, a wholly remarkable book, has very little to say on the subject of sleep. What caught Ford's eye was the referral to the subject of Dreaming. Which it in turn referred him to the entry on the Endless. He had, of course, never heard of the Endless, few mortals have in this day and age, and he was of course very curious to figure out what it was.
The entry on the Endless was very long, so I will summerise it for you:
Don't mess with them.
Ford decided it was high time he went somewhere new, and that the Dreamworld was the perfect place to go.
