Ive been having dreams of people who i am really close to or love dearly then wake up, then something happens then we never talk again. My dreams arnt giving me that sign though. some we are just hanging out and having a good time. I dreamt of everyone i was close to. even my cousin! and now we dont talk! we were the best of friends. Im scared to even think aout the person i like because i dont know if im going to dream about him or not! This ALWAYS happens. I dont understand.

It's possible, but I doubt highly you are burning bridges or should I say not speaking to people and losing friends because of your dreams, but rather more than likely what you are projecting to others. Perhaps the dreams you can't remember are your minds way of warning or reminding you that you need to take a different approach in how you interact with them.

On the other hand...

It's also quite possible that the people you think are no longer interested in being your friend are just busy with life and you are misinterpreting the fact that they are not available any longer... such as school, work, extracurricular activities, sporting events, etc... If your age is correct, school recently started, summer is over and you are 17 which would mean most of your friends are around your age and focusing on school, activities and responsibilities. Perhaps you're reading into it too much the fact they were available over the summer and now they are not as available as they once were. Perhaps they haven't abandoned you at all...
