Why do I keep dreaming of something and seeing it the next day?

Okay I keep dreaming of something and seeing it the next day. It's getting so annoying. The other day I dreamt of a bag of goldfish crackers and the next day at school I saw someone eating them. And last night I dreamt I was on a boat and was putting on sunscreen and today I was looking at pictures of Criss Angel on someone's page and happened to see a picture of him putting on sunscreen. I also dreamt that I was buying rice cakes last night and today I was reading something about healthy eating and I saw the word rice cakes. It has happened to me before but lately its doing this to me a lot. Does anyone know why this could be happening? thanks so much :)
