This has just been bothering me lately and Google can't find me a definitive answer.
This is what it looks like, (I'm assuming) when you look at a point of light at night.

This is what I see (with some gradient effect between each streak)

The streaks rotate with my head, so I know it's in my eyes and not outside, and I've seen these since childhood so I know it's not life-threatening. I just want to know if it's natural to see these things, or better yet if there is a name for this if it's not natural. Thanks.
