So I THINK I managed a WILD - but I'm assuming I completely misjudged when I have my REM sleep?

Took about an hour I was on my back, a simple mantra 'I will' while breathing in 'Be lucid' on the out. Anyway, all of a sudden I had a strange twitching feeling at the back of my head and my fingers and toes felt like they were twitching as well. I then entered what felt like heightened awareness , it was a lovely feeling , almost like the end of an orgasm, but prolonged. Anyway, I've never felt like that before, I felt sure that a dream was on the way.

But there was nothing - I even tried to form dreams form scratch, but nothing happened - so I can only oresume I was either too excited about what was happening, or it was completely the wrong time to try, or I hadn't succeeded at all.

Any ideas?
