Controlling Visions

Lately I've been having trouble with visions. I used to get them only when I was asleep, like I was dreaming, only the dream would happen later. Now, I've been getting them when I'm awake. One time I was swimming at swim practice and we were doing laps. All of a sudden when I looked up to breathe all my teammates were lined up on the side of the pool deck, cheering for me. I kept swimming and when I looked up to breathe again, they were gone. Then a few days later at the swim meet, when I looked up to breathe all my teammates were lined up on the side of the pool deck, in the exact order I saw a few days ago, and they were cheering. Another time I was sitting on the couch at home, watching TV. The next thing I knew I was sitting on a different couch that was brown, with some guy and we were holding hands. A few days later I saw this guy at school and he asked me out. A week later I went to his house and we sat on his brown couch, watched TV, and held hands, just like in my vision. Sometimes I won't even get a whole full vision though, sometimes I'll only get a picture of something or think of something random, and it'll happen. Since it's happening more often when I'm awake I zone out sort of. Sometimes I zone out for a long time, other times it's only like thirty seconds or so. Is there any possible way I can control when I get visions? Or at least help with the zoning out part?
