I was attempting to astral project for the very first time last night and noticed some odd happenings as I tried. My whole body felt heavy-that's normal but as it grew heavier my arms went numb and felt like they were on fire. Is this normal? Also, throughout the entire time I was trying to relax and exit my chest and head/neck would rise automatically and I would find that I had to keep forcing my upper body to stay on the bed. Not once did it feel heavy and relaxed like the rest of me. Is there something I can do to help this? (it's very distracting)
