Do you believe that dreams are signs?

I, myself, am undecided. On one hand, I have these crazy, absolutely random dreams, whenever I actually manage to fall asleep. Then if I am lucky, I'm not waking up, subconsiously talking to nothing but myself. I try to tell myself that it's just my brain acting by itself, fatigued by the day, and is acting in it's own way to wind down.

On the other, if dreams are signs indeed, then we can take Deja vu, for instance, much more seriously. We can allow ourselves to percieve our own realities, and hopefully see what our dreams are wanting to tell us.

What do you think?
