Abnormal paranormal experience may sound like a tautology, but this thread is for stories that don't fit under any of the main paranormal topics like aliens, ghosts, etc.

For example, One time a few years ago when I was first learning to meditate I opened my eyes after about five minutes of pure focus and saw a light in front of me.
It wasn't so much like a flashlight being shined in my eyes as it was like a three dimensional, fist sized diamond rotating in front of me and sending off rays of light in every direction.

So it was a very unusual experience.
