Today I stupidly played the fainting game, just once. the version I did is where you breath in fast for a min with your body limp and body slacked down, then after a min stand strait up and a person pushes against your chest area. I am now worried I may have damaged my brain. I never blacked out or fainted, but I did feel dizy and lighthead, felt like I was about to fall over, and my body was tingly all over.
