Impossible Sensations

I'm curious to hear about sensations that others might have experienced in dreams that would be absolutely impossible in real life. I've had several that I can never forget, even though they weren't "real."

Once, I dreamed of a boy with deformed hands who couldn't talk. Someone in the dream told me that if I touched his hands I would understand him. I reluctantly put out my hands for him to take hold, and as he did, suddenly I was overcome by a sensation that can not be adequately described in waking language. My own thoughts were shoved aside to make room for his, and suddenly I was seeing images that weren't originating from my own brain. The only way I can think of to describe it is "mental rape." In that moment, I felt like I knew what it's like to be raped, and I woke up in terror.

On another occasion, I was shot in the head. There is no doubt in my mind even today that the sensation accurately replicated what it feels like to be murdered in such a manner. I was counting money with one other person in an old house with wood-paneled walls, and we heard a couple of muffled pops come from somewhere else in the house. I knew they must have been gunshots, but they were just muffled enough that I thought my "colleague" might not have heard them. There was a staircase nearby, and I tried to rush up the stairs as if I had business on the second floor. Unfortunately, after I had gone only a few steps up, the other guy said, "What was that?" He was somehow superior to me, so I had to act on his question. I trotted back down and said, "I'll go see." As I was coming down pretty quickly, I was almost at a jog as I rounded the doorway into the next room. I came face-to-face with the barrel of a pistol and tried to duck away as I said in surprise, "Whoah!" Whoever held that pistol fired on impulse, and the shot struck my right temple at nearly point blank range. There were four simultaneous sensations that I can only describe one at a time. For one, my head was impacted as if I'd been kicked by a horse, and it flew backward with force. Also, I was painfully aware in a fraction of a second that my skull had shattered into my brain. Curiously, I only heard the first few milliseconds of the gunshot in my right ear, because my ear drum was instantly shattered by the noise. Finally, I also felt the powder burns on my face and neck from having been so close to the barrel when it went off. I say "finally," but that wasn't the end of the experience. I also felt myself slumping to the floor as my body slid down the wall, but my senses were now corrupted. I couldn't see, and I also couldn't really experience what was happening in the room anymore. I was vaguely and briefly aware that I'd been shot, but my awareness was rapidly closing in. The sensation was a bit like lights being turned off in a house as sections of my brain closed down. As that last tiny light of awareness was fading away, I woke up and sat straight up in bed with a gasp. Later, when I thought back on that dream, I realized that if anyone ever asks me "Head or chest?" like you see on the movies, I think I'm going to say "Chest." I get the idea now that a head shot isn't the quick and painless thing that most people think it is.

What have you experienced that can't have possibly happened to you in real life?

I've dreamt of being connected to everything to the point that not only was I myself, but my environment, its inhabitants and the dream itself. I've also had a dream in which my penis was cut off, and not only that, but I put it back on the stub and the skin on both ends morphed and bulged and stretched and it formed back together, reattached as good as new.

Generally for me it is a sensation of dream, it's unique and i can feel it when i am aware enough of dream and about to become lucid. I have gone through alot of experiences in dreams, lucid or not, but of more recent ones: being in the middle of nuclear explosion, and surviving, quite an experience i should say. :P
Also could add sensation of having completely different body/wings/tail, though i wouldn't consider it absolutely impossible since i do have some 'phantom' sensations IWL. :)
