Flip Flop wake up call

[Darth Wader]

I have a 6 gallon tank next to my bed. The tank only has one inhabitant a bicolour blenny. So I fall asleep last night and get waken up by the sound of something landing on my bed. Now my roommate has geckos and chameleons so I assumed it was a cricket, so I open my eyes and it the dark of the night I look to the side of my head and barely make out the silhouette of my bicolour blenny flopping around on my bed. I think to myself "What the hell" and so I quickly grab him and throw him back in his tank. Needless to say it was one of the weirdest things that has ever woken me up before.
