So, this is what happened:

After going to bed really late the previous night, I woke up at about 1pm on Friday, so I thought I would fall asleep really hard. I was wrong - I got into bed at about 9:30pm, read a while and then turned off the lights, shortly after that beeping a friend (call and hang up before he/she answers, I don't know if "beep" is the English word). That was at 10:02pm. The next thing I remember was this dream. I was in the front of this building I lived in during summer-camp last summer with a friend. It was dark and we saw a man coming towards the building. I could also hear his footsteps. My friend and I started giggling because we joked that mybe he is going to harm us (very dumb...). It started to turn darker and darker. The man's steps suddenly ceased and I got scared, I called for my friend but she wouldn't answer. Meanwhile, it had turned pitch-black. I realised that I was in bed.

Then, I believe I fell asleep again (maybe those firts phases of a sleep cycle...), until I fel someone sitting on my bed. I was sure it was my mother, though I had no idea why she would come to me in the middle of the night. I was sitting on my front and I felt "my mom" leaning over me. I felt pressure on my body and then I felt as if two arms were trying to wrap around y neck and I thought my mon wanted to hug me. Suddenly, I got scared and thought that someone wanted to srangle me and I tried to speak to reassure myself it was my mother but I realised I couldn't speak or even moan. That lasted one or two seconds. Then everything turned back to normal and I could get out of bed. I wasn't even too scared...The first thing I did was look at my phone, it was 10:38. I told my mom about my dream and when I returned form her room I saw that I had recieved a beep back from my friend, at 10:40 - not that this is important but it's a funny coincidence .

So, what do you think it was? Sleep paralysis or the early phases of a sleep cycle? And why did I dream? I thought one only dreams in REM period but I had fallen asleep after at least 35 minutes (even less, I rememeber thinking of a lot of random stuff and getting upset when I realised cause I would fall asleep harder if I did that).

Thanks if you can help and sorry if this post is confusing, please ask if you don't undersatnd something.
