Odd experience happening at night

So I've had this odd experience happen at night twice in the past month. So I go to bed whenever I am tired. These both happened when I wasn't very comfortable (due to heat and lack of leg room). I wake up about 2 hours later and I have these strange delusions that last until I can somehow get back to sleep again.

The first time this happened, I woke up very hot and sweaty, and uncomfortable. I was fully conscious and felt normal, except that I thought Germans and Japs were up to something suspicious... I thought they were like experimenting on me or something and that they were hiding guns in my house (btw, this all happened after having a, what felt like, long dream about me being in a war battle). So, I turned my TV on and was fully awake and aware, but still had the delusion for some reason (although, it wasn't as strong as when I first woke up). I tried getting back to sleep, but was unable to for 2 hours because I was so uncomfortable. When I finally did sleep, I was fine in the morning.

The second time this happened, the night before I was doing a lot of work on an algebra problem. I went to bed at midnight, and my dog was sleeping on my bed making my legs very cramped and uncomfortable. I woke up at 3 am, and like the last time, I was fully awake and aware. However, I forgot how to sleep and I thought I had to solve some algebra problem in my head to get back to sleep. I even thought that no one can get to sleep normally, that what I was experiencing was normal, which is odd. I finally fell asleep and was fine the next morning.

Anyone have any idea of what these were? At first, I thought it was a night terror but I don't think delusions like this accompany night terrors.

I actually don't this its that unusual. I mean if you felt like this in middle of the day then yeah, but you just woke up. A weird way of thinking about it is that you were in a reality created by you mind, like being inside your own mind, and then coming back to reality, so its not strange to still be in that state for a while after.

Usually after waking up I have some visual distortion, especially if I look at my monitor. I don't think I've ever had delusions like that, but I think its fine as long as you're sure they won't become a harm to yourself or others. But of course if it is uncomfortable for you and you hate it then you might want to talk to your parents or someone about the possibility of figuring out how to stop them.

I'm certainly not an expert on this though, I wish I could help more.

Yeah, I'm prett sure it's normal. I don't know what causes it, but it has happened to me as well, several times.

One time I stayed up all night reading Trickster's Choice and I went so sleep for about half an hour. When I woke up, I was convinced that I was the main character, strategizing with people in the room (who obviously weren't really there) about the Raka uprising. It took me a long time to snap out of it.

Another time I woke up and thought that Prince Carrion from The Abarat was in the room with me. I was having a conversation with him, but I don't really know if I was talking out loud or in my head.

two months ago i woke up to believe i was an african american in his forties,i then go to my bathroom and look and the mirror and freaked out because i had unusually pale skin for an african american, i then went to go back to my bed and couldnt go back to sleep becuase i was thinking what the hell happened to my skin, after about 40 minutes or so lying there i realised i am not black.

I think there are two different things that happened here.

With the first dream I think at first when you "woke up" you were actually still dreaming, but with your eyes really open and were having a sort of hallucination. When you really woke up you felt confused and the experience took a while to shake off. Thats my take on it anyway.

With the second, when one works intensely on a problem sometimes it ends up going round and round in our head. If you then try to sleep a part of your brain is still trying to work it out and it kinda gets mixed up with the part of your brain that is trying to dream and you end up trying to work something out that doesn't always make sense anymore. Thats why its best leaving problem solving to earlier in the day.
