Nothing computer related, hence the off topic haha. 

This is about actual sleep, the things we humans need y'know. 

For the last few months, I've been having some strange experiences in my sleep, in which I'd wake myself up as I'm sitting up in bed. Most times I'd have no idea why I'm sitting up, but I'd knock my head on the headboard or move myself too quick and wake up suddenly and be kinda dazed and confused. 

I've ruled out environment and bed because it's happened in my normal bed on a quiet part of town, in a spare bed at my mates house which is kinda basic but really quiet and with blackout curtains, and also happens at my boyfriends house, which he has commented on before, saying I have spoken in my sleep when doing that, something about what the time was (We both had work the next day rather early so I guess it was something to do with that). He thought nothing of it and said what time we were due to get up. I was partly awake at this point but not quite so just said "Huh? go to sleep" thinking he had woken up in his sleep too. 

After this happens, I usually can go down and be straight back to sleep very shortly without problem. Usually I can have no recollection of what dream I had before this happened, one time it was about my cat chasing my feet, woke up sitting up and the cat was at my bed (was there when I went to bed so not too strange).

So I'm here to ask, what could be causing this do you think? What could I do to fix it?
Its not bothering me too much, its just kinda annoying and I dont want Ryan to think I'm weird because I  do this haha. Any of you had anything like this? What did you do to fix it or what helped?

Thanks :)
