Okay, so it is kind of, but I have found out how to not be bothered by sensations that oughtn't bother me. Self-hypnosis. I use commands to block out any sensation that I don't like (for me it's almost exclusively sounds.) My blood pressure has dropped 20 mm Hg since I've stopped having to be stressed by my environment. Now, of course I know that whoever reads this will be uncomfortable with the idea of hypnotism. However, a) You have complete control over yourself during a trance. You can wake up at any time. b) You can choose to ignore commands. c) You will not forget what happens while in a trance unless you choose to. Being in a hypnotic trance is so similar to full consciousness that ~80% of people entering trances do not realise they are entranced. I had been hypnotised dozens of times before I ever knew that I was, after my therapist explained that a trance is simply a state of deep relaxation. It's perfectly safe and highly effective. If anyone's interested, I can give more details.
