Ive been trying to get lucid for a while now, and last night i got the closest that i have ever been...

Last night I think I got into SP , although there was nothing crazy going on, I just felt as if my body was heavy as hell.

I felt a "wave" come over me, but then i just stayed like that. I didn't really know how to push it through to a lucid dream, so I ended up just waking up.

Any advice on how to get through this?
Cheers
