I think at some point you will have to deal with this problem or similar? I would work on your self esteem and practical problems a bit before going to college so they were not suich an issue? There are a lot of pigeons in the world who will not get out of the way and one cannot just avoid them or route one's life around them all the time.

Some of your sleep talking might be stress-related overflow from trying to solve these sorts of problems all day and needing nighttime to help too. The only time I talked in my sleep was like that; I was at a conference and was practicing the language I had to use to give a special speech. One thing I would convince myself of is that people often laugh because they enjoy things, not because they are mean and there is something wrong with you. It is about the novelty to them, not you and that you are providing it. One of my roommates in college sucked her thumb and looked very sweet and vulnerable; I tried to tell her that but, of course, made a hash of it and she was very very angry, etc. and it wrecked the little bit of relationship we had. Something may seem "obvious" to one person but not be to the other and when we are in our teens and 20s I found we are not very good at wording things yet or knowing when to say something and when not to? All that takes experience and often experience is painful?

I think you will have to see if people laugh at you and what their laughter means and how best for you to respond? I was in my 50s when my roommate laughed at me for talking in my sleep so it was not at all traumatic but I found it funny too since it was unusual for me. I was not conscious so it was not "me" deciding to do that, etc. Anyone could have done it. My college roommate when I was 20/21 talked in her sleep but she had become a good friend, was comfortable with herself and knew she talked in her sleep and was not bothered by it or discussing it, etc. There are all sorts of different scenarios, use your imagination and think up a few that bother you and give them "endings" you like.

I like watching "How I Met Your Mother" on TV, they are always giving each other a hard time and pointing out mistakes and bantering back and forth but you get the "whole" where each person is both criticized/made fun of and supported at the same time.
