I woke up this morning with the Sun in my face, which marks the first time all year that that's happened.
(The irony, that I'm now listening to the Grateful Dead's "Looks Like Rain.")
And after a few seconds had passed (you know, it takes me a few seconds to realize that I'm not still in my dream, trying to navigate through some bizarre hotel corridor), I realized I couldn't read the numbers on my old LED alarm clock.…

Hayward's new article in Brain Research Bulletin describes all known tactile illusions. Some can be tried easily at home, but can work better when your gaze is averted and if someone else is performing these illusions on you (to reduce proprioceptive feedback):
The Aristotle: an object touched with crossed fingers will sometimes be identified as two objects (try it on your nose)
