Try to remember to breath when you are laughing. Sounds like a minor case of asphyxiation. "black outs" "seeing stars" "head rushes" etc...all are merely physical manifestations of physiological functions within the body. When you stand up too quickly, you get a head rush. When you laugh too hard and long...you will start to experience the physical symptoms of oxygen deprivation, or asphyxia. I don't think this has anything to do with hypnagogic hallucinations. |
