ha ha - the universe works in mysterious ways!

I really just wanted to bitch about the nose pinch RC saying that it 'aint all that - lol, but reading back to your first post I've since had similar experiences (I think) - I think it all comes down to belief - and the fact that you found it difficult the first time (for whatever reason) that experience is now cemented in your mind as a problem - which it is not - it is only our minds that create these barriers. You have a subconscious thought at the back of your mind telling you that you hope the slowing of hand thing doesn't happen again and because that doubt is there it creates that problem.

Remember - you are in complete control.

Another theory, which I've experienced a couple of times, is I believe you are in between states - waking and asleep. I've had lucids where I get up and walk around and it's like I am in a void - I'm just a consciousness floating in nothing, it only lasts for a few seconds and then I wake, sometimes the hand thing works and sometimes it doesn't.
