To help clarify, I get a weird sensation of pressure in my head and I can usually tell when this "shrinking" effect will happen once the pressure kicks in. It seems to happen a lot also when the book I read is in my lap or thereabouts and I can watch as the book will shrink in my hands and even my hands will look small and far away as if my arms suddenly grew an extra 2' of length.
It's not scary or anything since I can literally shake the effect off by just looking away from the book, but if I look back at the book within a couple of seconds, the process repeats itself until I can't go on reading anymore. If there is a name for this or if it is supposed to be some kind of preemptive strike from brain cancer (Heaven forbid) then I would really like to know.
I probably won't get a response, but I felt since it can't hurt this is the first place I am looking for any advice.
No, definitely not new. Yeah, that's why the internet is a scary place and you go to doctors to filter that out for you :)
Didn't mean to scare you, but like I said, go see a neurologist. Having had this condition for so long without any other side symptoms like migraines or seizures probably indicates it's not cancer or anything super scary though :P
Sounds like [micropsia](http://en.wikipedia.org/wiki/Micropsia). There are a lot of different causes for it. Is this sudden and new? Anything new you've done lately? New medications?
Edit: I misunderstood what you meant by your arms growing 2'. Not Alice in Wonderland Syndrome, but in the same family of vision disturbances. I would go see a neurologist.
