Another dream question?

I was wondering because i always found this weird when micheal jackson died i ad a dream a couple days before in my dream a news anchor was on the t.v and said today micheal jackson was pronounced dead and when i woke up i was shocked days later that it actually happened so my question is can a dream give you a glimpse into the future or was that some weird coincidence but i had the same thing when gary coleman died i just knew he was going to die but i dont know how and its kinda freaky
