A superstitious question from a non-superstitious person (details inside).

This is a dream question. Don’t kill me.
I know dreams are mostly made up of things you have seen or have been thinking of recently, and I don’t really think of them as much as I used to. But here’s my question:
Do you, or have you, ever let a dream determine your actions or decisions in life? I’m not talking about every other dream you have, I’m talking about a dream that you thought bore some significance to a particular situation or time in your life.
I’ve been having the same recurring dream for almost two weeks now, and it’s pretty silly, but it’s about my topic choices. So I was just pondering why this is.
