The other night, something odd happened as I was about to sleep. I turned off the light beside my bed. The only other light is a faint orange glow from the on/off switch of a powerbar at the floor. I closed my eyes and I saw splashes of colours moving around. There were silhouettes of something short and worm like moving around. I thought I was already in a half awake / half asleep dream world. I opened my eyes and saw darkness. I closed it and all those colours appeared again. I repeated it several times with the same result.
Shortly afterwards, I fell asleep. The next night, those colours appeared again but were almost bleached out. They never showed up again.
Hopefully I’m not going crazy.
