Also, some time ago, the maid was afraid to go in my room and I had no idea why.

You have a maid? What the hell, dude, what the hell.

I have conversations all the time that I forget because I was asleep and then SUDDENLY remember like ten hours later. The problem for me is that the memories of the real conversations seem to be exactly the same as memories of dreams I've had about conversations, so I never know which is real. My family has pretty much stopped trying to tell me to do things before I am awake, instead leaving notes around the house.

One thing I've noticed I do a lot (I always check the time when I get up) is I check the time in my dreams and think that is really the time. The scary thing is is that I am rarely that far off (usually around fifteen minutes) despite not having a clock in my room (I use a watch next to my bed that I have to pick up and check). This morning I actually said to myself "oh, it's this time" and then I said "no it's not, I'm only dreaming, get up Andrew, get up!" and then I got up and checked the time and I was 20 minutes off.

I remember I woke up thinking my cell was ringing when it was actually my alarm clock which was ringing. I then searched for my cell (which took a minute or two), opened my cell, realised that my cell was off and that it was my alarm clock which was making all the noise, shut off my alarm, and went back to sleep.

I got to school 3 hours late.

I almost suffocated once. Yeah I really dont enjoy sleeping face down anymore

also

When I was little when Id go to sleep, Id generally wake up in a different place, like the floor. I dont really know of much crazy things about me but my sister was running in her sleep once.

I had a dream that I was beating the hell out of someone, and when I woke up, I felt one of my arms take a swing at the air.

The past few days, I have been waking up 5-10 min before my alarm clock is set to go off. What happens is that I dream my alarm clock didn't go off and I woke up like 5 hours late, and immediately after, I wake up for real and check the time.

Yeah, I've had this happen. I've woken up and realized I was actually swinging my arms through the air. I wish I had these dreams more often to give myself a sweet workout. 

Yeah like someone was saying sometimes I'll be dreaming I'm with someone cool or in a cool place but then I get awake enough to realize it's a dream and I'm like shit

Yea this happens to me a lot too :[

I don't know if this counts, but...

One night I was having one of my funny dreams, of which I have many. In this dream I was back at my old primary school (I'm 20 now) and I was talking to one of the kids, Damien, who I didn't get on with (Damien is actually a real person). For some reason I was pissed off at him in the dream, so I did what any intelligent person would do - I punched him in the face ​.

Now heres the weird part. I have a chest of drawers next to my bed. At the exact moment I punched dream-Damien in the face, I had actually leaned over and hit the wooden drawers with my fist. Hard. Needless to say I woke up immediately, moaning 'ahhhhh......f**k!'. The pain...my fist was throbbing like mad.

I eventually went back to sleep. I checked my hand in the morning - the knuckles on my thumb and first two fingers were skun pretty bad, and there was a big blue-red mark on the inside of my fingernail. It was a bruise or something. This mark only grew out a few weeks ago, and that was a good couple of months after the incident.

So yeah, I thought that was pretty wierd. I also punched a wall when I was sleeping in someone else's bed a few weeks later, but that wasn't as bad as I only hit it softly.

People who know me know that I'm an insomniac.
But I can sleep through everything when I do manage to hit the bed.
I've joked that if there is the End of the World or something someone had better wake me up, or else I will miss it.

When I am upset, though, my sound sleeping goes right out the window.
I don't consider this unusual. I expect that everyone must have once had a bad night's tossing and turning like I do sometimes.

However, one peculiarity of my interesting nights is one that I haven't heard people admit to -- panic attacks.

When I am emotionally upset and go to sleep, I will sometimes wake up in the middle of the night in an absolute panic.
Usually, this is either due to a (false) sense that I am late for school, overslept, etc..or if I dream about someone that makes me feel uncomfortable.

One time, in Turkey, I managed to wake up -- SUDDENLY, grab my clothes and make it into the bathroom to turn the water on before I realized it was 3 am.

One night, I woke up in a false panic that I didn't know what time it was and that my clock was wrong.
I looked on my arm for my watch and got upset that it wasn't there even though I broke the band some time before and haven't yet replaced it.

These sorts of nocturnal things are just-- Fucking odd.

Not sure if this is the kind of thing you're looking for, but I sometimes fall asleep with one of my arms under my head or some other part of my body, cutting off circulation. When I wake up, my arm is completely numb and I can't feel it at all. At first, I usually panic and go "where the fuck is my arm" and once I realize it's still there, I move it around with my other arm since it can't move on it's own. It becomes very limp and I feel like a part of my body is dead. Pretty cool feeling.

I LOVE IT when that happens.

It feels so weird swinging your right arm in the sky with your left arm as if isn't your arm at all -- it feels like you're holding a corpse's arm wtf. I've eventried and purposely slept in such poses that I'd intentionally cut off circulation to my arms and i'd then wake up in the middle of the night - jump off my bed and actually feel arm-less for a few moments. My arms then feel like they're clinging onto me like partially cut-off joints -- it feels FUCKED UP for sure, but oh so interesting.

I'm not fully aware if this might actually be damaging to any nerves or muscle tissue in my arms, which would sound very logical as oxygen supply gets blocked to them though. I also suffer from low blood tension, meaning my blood circulation is simply a lot easier to obstruct than for example someone's with a high blood tension.
