You ever see a picture of that Vietnamese monk self immolating? I am pretty sure it can help with sensory issues. It definitely helps me.

I'm probably not doing it right or progressing really but I read a book years ago and started doing just 5-10 minutes a day of beginners Samatha meditation. I haven't really done it formally for a while now but the perspective is still with me. I did it for a few years. Forget the metaphysical stuff. Focus on your breathes. Start by counting them through 10 and back to 1, in and out, and watching them for their different qualities. Are they short or long? Are they in your abdomen or chest? It changes all the time. After you relax a bit start at the top of your head and do a slow body scan all the way to your toes taking about a minute. You'll notice aches and pains ant stiffness and asymmetry in your body and posture.

I get hung up on sounds as well and I find it can help me to stop trying to run from the sounds and try focusing on them instead. If there are to many voices just focus on one. I used to think meditation was about floating out of your body and into space but it's really the opposite. Its helps to ground me by helping me to notice my body and not chase every thought. But I think most importantly don't judge anything that you notice. Try not to categorize things into good and bad. Shit just happens. Nobody else is in there with "you" but at the same time everybody else is in there with you.

It helps to create a level of abstraction between your "self" and this "watcher" that's noticing all of this stuff. When thoughts come just acknowledge them and let them go. Every thought is not important. We make a huge excess of thoughts. They can be useful in an emergency but usually they aren't very useful.
