...cant move etc? Hello, sometimes i wake up in the middle of the night and i see black shadows in my room, and it seems like theyre moving, so i stand up and start screaming, swearing and start trying to punch things, then when i finally find the light after everbody in my house has woken up and rushed to come and see me i realised nothing was there, and also sometimes i feel that i am awake, but cannot breathe, cannot move and i have to struggle and struggle so much that i can move and breathe again, Please can somebody help and tell me what this may be?
