I See Things When I Meditate.

When I started meditating some 25+years ago, my first experience I saw what appeared to be a wizard or an old bearded, long haired man, flying through space (or nothingness). He was carrying an orb. It happened quick..and I had a sudden feeling in what I assume was my 2nd chakra from the bottom. It was akin to an orgasm, but different. Sexual energy for sure. I think it was a kundalini release.
After this, they mainly were just deep disconnection from the mind, and when I'm meditating I usually see two colors, moving sort of like the fluid in a lava lamp. Odd colors, shades of green and violet. the green one is bright and obviously represents something special.
