Tony woke up lying on a mattress, with a pillow under his head.
Huh, so I did make it into a bed last night, he thought to himself, yawning. I thought I fell asleep at my desk. Didn't I?
Stretching his arms out, he felt a body next to his. Tony froze, and began attempting to recall the events of the previous evening
I didn't drink last night, did I? No, I was in my lab, working on the gauntlets. No alcohol, no. He could not taste any alcohol on his breath, nor felt any of the adverse side effects of alcohol. Definitely no alcohol, so this is no hallucination. I was working all night, and then fell asleep on the desk. What the hell? Why am I in a bed with someone? Who am I in bed with?
Opening his eyes, he rolled over to look at the body next to his. The first thing that he noticed was that his bed partner was female, and had extremely familiar red hair.
No, no, no, no way! Tony's breathing picked up, and he began inching slowly away. I am not in bed with the Black Widow. No, no, not possible. Not in any way remotely possible. Nope.
When the body began to roll towards him, Tony rolled away, attempting to get away, before he ended up rolling off of the bed, and landing on the ground face first. Internally groaning, he rolled onto his back, before sitting up, and began to rub his aching face. He then decided to hazard a glance at Natasha, who was looking at him with an eyebrow raised, seeming to not know what was happening either.
"Natasha, why are you in my bed?" Tony tried to say only he heard no sound come from his mouth, nor could he hear any sounds at all. What the hell?
He saw Natasha's face over him, and saw her lips moving, but heard no sounds coming.
That's it, this has to be a dream Tony thought, shaking his head. Yep, just a dream, Tony. You're clearly still in your workshop, and worked yourself to exhaustion. It's all just a dream. There is no other explanation.
He tucked his knees up, resting his head on them, resembling a ball. Ignoring the woman still sitting in on the bed above him, he tried to focus on his thoughts. Just a dream. You'll wake up in your workshop soon, and then you can have a cup of coffee and forget about the lack of sounds. Wake up, and play some music full blast. You are not deaf; this is only a dream.

Bruce had always been a light sleeper; it helped when you were on the run. Despite living in the Avengers Tower for the past year, he still retained the habit. Even the slightest sound would wake him, and a touch was sure to cause him to be alarmed.
His eyes shot open, rolling his head towards the body next to him. Apparently the body was more nervous than he was, because they rolled away, ending up falling onto the floor loudly. Bruce winced, he fall must have hurt.
What have you gotten yourself into banner? He thought to himself, unable to remember how he had even ended up in bed with someone. He pushed himself across the bed, to see if the mysterious stranger was alright.
Looking down at the person on the ground, Bruce was rendered speechless. I slept with Clint? How did that happen? Bruce shook his head, trying to recall the previous evening. He remembered going to sleep in his own bed. So how did I end up here?
He then saw Clint moving his mouth, but no sounds came out. Bruce looked at him worried.
"Clint?" He asked, but the man on the ground did not respond. "Clint, what's wrong?"
Still he received no response from the archer on the ground, who looked incredibly panicked.
"Clint?" He asked again, noticing for the first time that he was not hearing his own voice. The voice he heard was... Female?
What? Why is my voice female? And so familiar. Where have I heard hat voice before? Bruce thought, before putting together the pieces of this puzzle. Looking back down at Clint on the ground, he shook his head.
"No, it can't be," he muttered to himself, bring a hand to his temple. He frowned at the touch; the fingers were definitely thinner than his own. He held out both hands in front of his eyes, looking at them more closely.
Well, these are definitely not my hands, he thought to himself, turning them over in front of himself.
He shook his head. "It's just a dream, Banner. Nothing more."
He decided to try and wake up from what was clearly a dream. He got out of the bed, and walked to what he assumed was the bathroom. He spared a glance at Clint, who was still curled up on the ground, shaking his head. Upon entering the bathroom, Bruce was not surprised to see Natasha's reflection in the mirror before him. He gave the reflection a smile, an expression that he had not seen on the spy before.
"Quite a dream, Banner," he muttered to himself, before running some cold water to splash onto his face. Nothing. Bruce frowned. I was sure that that would work. He decided to try pinching his arm, but still nothing.
"Uh, JARVIS?"
"Yes Agent Romanoff?" The AI responded. Bruce looked at the reflection in the mirror, raising an eyebrow.
"So, not a dream?"
"According to all readings available to me, you are indeed awake, Doctor."
"Damn." Bruce pulled the red hair to the front of his (her? Oh who knows, this is clearly beyond what I am able to deal with alone) body, twirling it around his finger. "Well then, I suppose that we should call a team meeting then."
"Very well. For what time?"
"ASAP. This needs to be dealt with."
"Very well. The message has been sent."
"Thank you JARVIS." Bruce sighed, looking in the mirror one last time before returning to the main bedroom, where Clint was still curled up on the ground.
Well, Assuming that that is Clint, of course.
Bruce sighed, rubbing the bridge of his nose. I think today is going to be an extremely long day.

Oh wow. So, I have not published in... a few years. And, this is my first Avengers story. (And the first time posting under Humor. That could be interesting.)
Based on the episode description of the next Avengers Assemble episode- the mind stone swaps their minds. So, naturally, my mind decided to think about how they would be swapped, and then this happened.
Naturally, I'm a bit rusty. Constructive criticism would be appreciated. Clearly there's more to come. And it will.
Question- can anyone guess where the other four Avenger's minds have ended up?
Thank you for reading.
