i have heard a lot of people say that in their dreams they do experience Mild to heavy pain. i have not experienced any pain in my dreams. in a dream a few days ago (not lucid) a guy tackled me and started chopping my chest with a hatchet. but it was going right through me. (i should have used it as a dream sign)

does pain only occur in lucid dreams? or does pain only occur when you believe it can?
