you were WILD-ing. In other words, you were falling asleep while you were still conscious. When you WILD, you get three types of HI :
Visual HH - you see pictures and images floating by
Acoustic HH - you hear weird noises
Semantic HH - you get weird feelings.
All that happens normally when you sleep, except you lose consciousness. When you say you had a delayed response, it was because as you sleep, at one point your brain shuts down all connections to your body. This is called SP. You were either ‘reaching’ that part, or you were experiencing SP, and then you had awoken.
In other words, you were very close to an dream where you would have been lucid from the start. Why don’t you try WILD-ing purposely, seeing as you got good results from the beginning. I’m glad to see you were relaxed and ‘you went along with it’. Go to the main website and read the information on WILD. You can also search for WILD topics on the forum.
