I almost never remember dreams. The last one I remember happened quite awhile ago, and I can't remember any before that... but in that one I dreamed that my cat died. So, the next day I decided to take it to the vet, and they were saying that it probably has cancer, heart disease, or kidney failure. All of which would be fatal. Thankfully, she ended up having Hyper Thyroidism, which is just a minor inconvenience, so long as we got it treated, which we did thanks to that dream. I don't believe that dreams carry any messages that your brain doesn't already know, but in this case, I'm glad I listened to it.
