I was lying in bed, browsing thorugh the internet while suddenly a flash of green light lit up the area right beside me, and out of the corner of my eye I saw a ball like this, only more neon in color (think ben 10's omnitrix but a lighter shade) appear about a feet from my head. It was just there for about half a second, and it looked like a hollow saturn, with a bright white spot inside and the surface of the sphere was translucent lime green (idk how to draw that so I did as good as I could, I'm pants at drawing). Then it imploded and sent a flash of blinding light all over the room. I don't have any electronics next to me and my phone couldn't have made that light. Oddly enough I had been feeling sleepy, but after that happened all the sleep has just went away and I'm feeling a little refreshed as If I just took a 2hr nap. Still scared though.
