I couldn't wake up...

I was taking a nap and when i went to sleep i thought i was still awake. but in the dream i laid down and went to sleep. After that i was inside a classroom. The room was dark and a screen was behind the teacher playing something. I couldn't make out what it was. But i was smoking pot and the teacher called someone. All i heard her say was "Never mind, i just need to talk to you about the drug enforcement issues". So after that i left the classroom because i didn't want to get in trouble. As i was walking down the hall another teacher looked at me and said lets get this student a desk. I just kept walking. Next i walked by a middle-eastern lookin teacher who asked me if i had an envelope he could use. I said no but i can take you to the supply room and get you one(Which was weird because to our right was an entire table of different envelopes). So i took him to the supply room in which another man was standing. He looked at me and said lets get this man an envelope. Right after that my eyes opened and i was back in my room. I wasn't awake though. I couldn't move and i could barely open my eyes. All of a sudden i felt somethin pushin from underneath the bed where my feet were. It just kept slowly lifting up and down. I started trying to scream wake up over and over again but it was like i lost my voice. I finally managed to lift up a bit but then i fell right back down and fell asleep again while i was still in my dream. I woke back up and started tryin to scream again to wake up but the same thing. This time i heard noises behind my head. and it scared me even more. Finally i woke up for real. Does anyone have any idea what this dream might mean?

It seems like what you have experienced is known as Sleep paralysis, its a boundary between being awake and asleep. Sleep paralysis can make you believe someone is in your room with you, or someone holding you down, basically your body can't move or speak because you're paralyzed. Don't worry, even though it may be scary, you are in no danger whatsoever, less struggling while in this state can make you wake up alot easier.

Paradox is probably right. Its happened to me once a long time ago as well, and it is rather terrifying, and it happens to my friend quite a bit, she absolutely hates it, but as far as I know its nothing to worry about. :)

It's the first time it's ever happened to me lol. I've had dreams where i've dreamt within my dream before but never like that. I believed i was actually awake until i realized i couldn't move and the bed started pushin up and down. My sisters religious and her explanation was of course religious. But i'm not a very religious person so i wanted a logical explanation and i thank you for replying with something that makes more sense to me.

No problem :). I bet your sister said demons are coming after you, it is popular to christians that if anything occurs like that, to have an explanation of demonic possession, in turn its just a stage from transitioning from being awake to sleep or vice versa.
