I definitely have a sixth sense. I always know when it is dark outside. I took a shower in pitch black tonight - usually I very much enjoy them. But the extra darkness just creeped me out. TOOO much darkness. I couldn't enjoy nice cool water and feeling my way around the shampoo and soap and razor (best shave ever when you aren't relying on your eyesight ;)).
But still - I encourage everyone to take a shower in the pitch dark at least once. Though, I should hope you get to know your way around the bathroom first or it could be pretty painful - OOF! Toilet! My priiide! :)
