A friend of mine recently mentioned to me (in confidence) that she's been having really weird sleeping behaviour recently. She told me that they're similar to nightmares, only she feels there's a large element of consciousness in them. She'd be "asleep", and she'd feel like she was falling while still on her bed, and she'd try to scream but would be completely incapable of moving or talking, she'd then snap into full consciousness but have dead arms or legs, and have the feeling that everything she just felt was completely real, and one time she had to go and ask her mom in the middle of the night if she'd heard her screaming, because she wasn't sure if what she was experiencing was real or not. We had a bit of a search on the net, and didn't find much, only something on "semi-paralysis", where during sleep, you have phases where you're aware to a limited extent of whats going on around you, but your body is paralysed to the same extent it is while asleep (ie. when you command your brain to do a movement in your dream, it only carries it out mentally, but not on your physical body). I know that's a not a great explanation, but has anybody heard of anything like this before, and what its associated with/caused by? She's been having a bit of a traumatic time recently, she was beaten by her Dad on Saturday night, resulting in a break-up of her parents, which is obviously taking a toll on her mind, but I don't know if its directly related to her sleeping problems, since she's appears not too affected by everything while she's awake.
