This is starting to bug me alot now. I've developed pretty good dream recall and have had 5 lucid dreams in the last 3 weeks. But now 3 of this dreams have been short ones where i'm stuck in my bed and can't do shit! The thing is, i am compelety lucid since i do reality checks and stuff and everything around me is clear, it feels like real life only that i can't move! This night i tried doing everything step by step like, first i put my hand on the side of the bed and well, i didn't see my hand so i said very load: See hand! hehe but i only saw a short glimpse of my hand then it dissapeared. And i went on trying different methods to get out of my bed but it didn't work so at last i just closed my eyes in the dream and i somewhat slipped in to a regular dream and eventually woke up...

Wtf is going on, why can't i just get out of my bed and start doing whatever i want?

I hope someone knows something about this? Please answer if so or give me your theories of why this is happening?
