I get like this some times. The sound of the fan, my dog snoring, the tv being just a bit too loud....I think I have a better sense of hearing than others here. It usually happens at night when I'm trying to decompress so I'll just get up and leave the room instead of getting pissed. I don't get the smell thing but I do get hyper sensitive to touch. I do not want to be touched. At all. Even by my kids. I get very irritable.
