Another reason why I ask about WILDing is because I have never experienced SP before and not even sure if what I experienced was SP? At first I was relaxed, then I was tingly and then I did feel numb but my only problem is trying to stop myself from waking up when my heart races. I had it again last night but not much for the hypnagogic imagery I'll try again tonight but I've been trying just before bed so should I try it when I wake up from REM sleep?
