hey man, quite new to LD'ing too. ive been trying for just over 2 weeks now. I think i know exactly what you mean when you say "shivering all over", i was having a bad dream and i woke myself up (so i was in the middle of a REM period) and i decided to fall back to sleep conciously for the 1st time and it pretty much worked! as i was conciously entering the dream world i could hear people talking and cars driving past. But i decided to do a dream stabilization technique too early and as i rubbed my hands together in the dream i got like a extremly tingeling sensation run through my whole body and i woke up! is that the same type of feeling as you? if it is, i dont think its a bad thing. i actually think its good i think it was the feeling of me entering a dream consiously but i got kind of supprised and exited that "shivering" feeling has happend to me twice. hope it helped. please reply
