Am I the only one who’s been reading this thread thinking “Oh, please, let me remain unique”? And, so far, I have, barely…
(1) On car trips, I look out the window with one eye open and watch the poles and stuff go by. And I also concentrate on a particular spot/smudge on the window. Because I only have one eye open, if I switch eyes, I can make the smudge jump either ahead or backwards with respect to the background. I then attempt, by judicious eye-swapping, to keep the smudge from ever actually going through a pole, the edge of a building, or any other obstacle. Rather, it has to jump over all such obstacles. (This is very similar to what Duct Tape King does, but it sounds like he does it by moving his eyes or ducking his head, whereas I keep staring in the same direction, keep my head still, and just switch which eye is open.)
When there’s a wide open space with no poles, I can open both of my eyes for a while, resulting in there being two little spots for a while. It’s like a breather out in the open between the high stress areas…
(2) Somewhat similarly, when reading and scrolling down a file on a computer (often an SDMB thread), if I’m using the little wheel on the mouse, I always try to position the cursor so that as the wheel turns a click and the page jumps up a bit, the cursor always is either in a block of text or in open space, never on a boundary
(3) Sometimes when I’m listening to music, I’ll finger along to it with bassoon fingerings. But that’s pretty normal and understandable (among people who played the bassoon). More obsessive is that sometimes I’ll finger along with it using the fingers of my left hand, with the following restrictions:
(a) my fingers are sorted from lowest (pinky) to highest (thumb)
(b) if the next note in a song is higher than the previous note, I must move to a higher finger, and vice versa
(c) When the music is going higher, and then hits it’s highest note and goes lower, the highest note always has to be on the thumb. And vice versa with the pinky
(d) The sequence of fingers from each occurrence of thumb to pinky or back must always be symmetrical around the middle finger. So a string of 4 increasing notes must always be pinky ring pointer thumb.
So, numbering the fingers for easy communication, Mary Had a Little Lamb would look like this:
531355511135542135555511531
This basically requires knowing the music well enough to predict ahead of time how many notes higher the music is going to go before it starts going down again. If there are three rising notes, it has to be 1 3 5. If there are 4, though, it has to be 1 2 4 5. This is particularly tricky when a phrase ends with a rising string of three notes, but then the next musical phrase goes even higher from there.
A further wrinkle is that some songs have more than 5 notes in a row rising or falling in pitch. Joy To The World, for instance, begins with 8 notes all descending. This can be managed by adding intermediate notes that require two fingers simultaneously. So you get note 1.5 by pressing finger 1 and finger 2 simultaneously. So Joy To The World begins:
5 54 4 43 32 2 21 1 2 3 3 4 4 5 5 5 4 43 32 32 2 1 5 5 4 43 32 32 2 1 1 1 1 1 1 3 5 4 2 1 1 1 1 3 5 4 2 1 5 4 3 2 1 5 4 2 1
(I can’t believe I typed that all out… and anyone who fingered along, I respect you
)
(4) You know how the word “passerby” pluralizes to “passersby” and “attorney general” to “attorneys general”? Well, I sometimes mentally pluralize things like that even when they shouldn’t so pluralize. For instance, I’ll mentally replace then line “You other brothers can’t deny” from Baby Got Back with “You others brother can’t deny”.
(5) When I’m looking at a large repeating pattern, most commonly the holes in the ceiling tiles, I’ll cross my eyes and view the pattern in “magic eye” fashion, screwing up my depth perception
(6) Vaguely similar to people who imagine their actions being viewed by someone else inside their body, I’ll sometimes wonder what other people could think if they could see my skeleton right now, but not any other part of my body, nor my surroundings. Could they quickly deduce that I was showering, or watching TV, or playing a board game, from just the positions of my bones? Also, if I’m going somewhere to meet people, I’ll imagine that they have a little maxthevool-sensing device that gives them the precise heading and distance to me… so usually the distance will be decreasing, but sometimes due to the layouts of freeways or whatever, I’ll go right past them for a while before turning around…
