Within the first like 10-15 minutes of laying still, eyes closed and earplugs in my entire body is numb... It feels cool but I can't enter SP. I KNOW what SP feels like but I can't go in. I can be numb for an hour and a half and constantly repeat to myself "I will have a lucid dream. I will move from waking to lucidity." The whole time but I can't enter SP what am I doing wrong?!
