Sorry if this isn't allowed but I was just wondering if anyone else experiences this? It's like I'll be laid down or stood still then it feels like my head, sometimes my whole body has just dropped like in an elevator. It's usually just my head and lasts for a split second and makes me feel a little disoriented afterwards. Someone suggested it could be bppv but it doesn't happen when I move, just when I'm laid/sat still. Did some googling and came across this which describes the sensations perfectly. Obviously its a huge relief because my silly little brain decided I was dying. Just wondering if anyone else experiences this?
