i agree with the post above. its extremely hard to WILD when u do it right before u go to sleep. i was having the same problem and would end up with my whole body feeling numb. what i think is that ur trying to lucid dream but ur REM really hasnt started kicking in yet making it very difficult. try getting some sleep for like 5-6 hours and then wake up stay up for like 1/2-1 hour and then try to WILD. it worked for my last night and i actually had 2 lucid dreams that i can recall in one night and those were my first ones.

the only hard part is that u dont completely fall asleep after waking up after 5 hours because its hard to stay up and be focused on it. but its extremely easy and its the only way that worked for me. most of the other methods gave me the feelings u've had. maybe u should give it a try? and tell how it goes
good luck =)
