Do i have any problems?

I have this thing about dirt, every night i will get up and wash my hands over and over, i don't know why. If i am alone, i check if i turned the gas off, and then i would check again, even though i know its off, i also have to wear socks because i don't like to touch the floor, and i always have these strange things, like if i am closing my door, before it makes a sound, i have to touch the carpet
