strange sensation: my head feels like its floating
Sometimes, I get this strange sensation in my head, where it feels like my head is floating upwards, or like im flying. sometimes this is accompanied by tingling of the scalp, and very rarely, dizziness. its a great feeling, unless I feel dizzy or have a headache afterwards. also, im not taking any drugs or alcohol when this happens. Is this normal, or is something wrong? also, does anyone else feel like this sometimes?
