There are many different experiences, and from a mystical perspective, infinite forms of yoga. Your comment seems to suggest that this is a normal sensation, but for me, it felt anything but normal.

What I’m trying to clarify is that while I did feel a very strange sensation, I wasn't necessarily describing the same thing you experience regularly. When I look into descriptions of third eye sensations, they don’t match what I felt, which is why it remains a mystery to me.
