I have as well, though most of mine have come in dreams. I dreamt that my best friend was moving away months before she decided to.
A few nights ago, I was taking my walk, when I realized I had to go. It wasn't bad, but I figured, let me go inside and take care of it so I don't think about it. Anyway, I go inside, and immediately smell gas. I find that I had left one of the burners on. I don't know what would have happened if I hadn't come back...maybe nothing, maybe the place would have burned down, maybe the pets would have died from gas inhalation...and while it wasn't a premonition, it was more like "divine guidance." In any case, I'm really glad I had to go at that moment!
