I can not believe the audacity of some of you, you should be ashamed.
iwasbitten - The human brain is wired to recognize things like symmetry, patterns, and human faces. Alot of people can have things like tumors or disorders like schizophrenia which cause them to overely experience these things. I don't think your crazy, I don't think your stupid, I think theirs something in your brain you don't know about.
Please the first thing you should do is go to a hospital and get an MRI or catscan to see if you have any tumors, systs, or anything else going on in your head to distort your thoughts.
If you cant find anything speak to a psychologist, trust them they can find a medicine for you and you will be much calmer and more content with your life.
I'm sorry as i'm sure people have ridiculed you alot. Your not crazy, you just don't understand why your brain is "freaking-out"
You will be okay just please seek some medical help. get that brain scanned, if nothing comes up talk to a psychologist and tell them everything. Hold nothing back.
