Hi there

I'm new here (18years old) and I'd like to tell you all my experience that I had yesterday evening. So yesterday I really read a lot of information about lucid dreaming and I was like "today I'll start my journey to the world of lucid dreaming!" In March 2012, I already had started a dream journal, but after about 3/4 dreams I quit, because it didn't seem to work. Now I'm back, full of confidence that someday I will have my first lucid dream

So yesterday evening I was ready to do the WILD technique, which I thought was not going to be easy, because I had tried it before and it didn't work. So yesterday (with confidence it was going to work) I was laying in bed with earplugs in playing isochronic tones. At a very low volume of course. I start to relax, close my eyes and start saying to myself "I'm going to have a lucid dream" and " I'll stay conscious while falling asleep". After some time (a couple of minutes) I started to feel really heavy, like my body was made of stone and I was being pushed INSIDE my bed. Also, suddenly everything became much darker within myself; like "real" black 360°. But I felt that myself (my conscious self) was still there.So on one side I was thinking "wow it's starting to work!" , but on the other hand I really started to panic...my hart started racing like crazy! I became really scared, because of how dark it became and had the feeling that if i didn't resisted, the darkness would take me and then there would be nothing to do about it if I'd let in to the feeling. So I resisted and I "woke" up again (even if i didn't actually fall a sleep).
It sounds silly but I was really panicking at the moment, because how dark it was. Like demons and other dark entities would take me...So yeah...Any ideas why this happened? And how I can cope with this darkness feeling and how I should relax?
It would be much appreciated!

Greetz!
