Actually it’s the satanic leaf-tailed gecko who sees you when you are sleeping (and knows when you’re awake). Ignore all suggestions to the contrary. Via rhamphotheca:
The satanic leaf-tailed gecko (Uroplatus phantasticus) is the smallest of 12 species of bizarre-looking leaf-tailed geckos. The nocturnal creature has extremely cryptic camouflage so it can hide out in forests in Madagascar. This group of geckos is found only in primary, undisturbed forests, so their populations are very sensitive to habitat destruction. Large Uroplatus species have more teeth than any other living terrestrial vertebrate species.
