Sadly I remember most of my dreams and they are not always pleasant.

But I do have regular dreams that are I think triggered by the seasons. In spring I have "storm" dreams where there are tornadoes or I get struck by lightning.

Summer time I think of being back to work for an old employer. It was a very happy time for me then.

Winter dreams mostly are about places I've been.

The rest of the time usually are of nightmares. It is odd thought, I normally am not frighten of them. They are just bad dreams of evens long ago with a different twist.
