Powers Changing

So I am aware that I have something called precognition. But it supposed to happen while you sleep right? Well lately it's been a bit different.

I used to always remember what I dream. Now I don't remember anything. I haven't had like these dreams of the future for about a month and that quite odd. So a about a 2 weeks ago I had a vision but not while I was sleeping it was while I was awake. It was so strange. I was just eating my cereal and I suddenly had this gut feeling and a few seconds later I just blacked out. I saw how I was walking into my class on the first day of school and I saw a lot of new faces, new people. It was just like a few seconds long. And then a few days latter it actually happened EXACTLY how I saw it.

And yesterday I was reading a book. I was reading like how this one girl was cheating on her boyfriend with this other guy and like suddenly I had this feeling/thought like I just knew that he is somehow evil and he will betray her and like 20 pages later he did. And later on the book it was so boring to read it because I just knew what was going to happen later and I knew how the book was going to end.

I just wish I could control it and use it on a daily basic or something but it just happens! Like when I'm in school I sometimes try to predict what's going to happen and nothing ever comes but when I'm alone it does. Its really weird for me cause I used to predict things through my dreams but never visions. Only once. But still its confusing. Any ideas how to "make it happen" like whenever I need it to? Thanks =)
