Why do dairy products suddenly taste bad?

I have a weird problem that happened to me once when I was maybe 8 years old (I'm 20 now). I woke up one morning and all dairy products tasted horrible. They tasted as though they had gone bad. I'm not sure how long it lasted back then because I just stopped eating all dairy products for a couple of years — I was afraid they would taste bad, but it definitely lasted several months. When I started to have them again they tasted fine. It seems to have started again. What could possibly be the cause of this?


Do I have ESP?

Sometimes at night I'll have a dream, and then it'll happen! There's no knowing if or when it will happen, but if I have a realistic dream one night, it's bound to come true at one point or another. For example, in first grade, I dreamed that I was in a place I had never seen or been in my life. I didn't even know it existed. Then, in third grade, I walked into the room that I dreamed about in first grade. It was the computer lab of my new school. Or I could be walking down the street and meet someone I have only met in a dream, in the exact same scene as the dream. It is all very confusing, and I think it may be either some sort of precognition or a mental disorder. Could you please tell me why this happens?
