I have had reoccurring dreams about hunting and flyfishing.
The general theme seems to be that I only have a little time to get ready and hunt before it gets dark, then something goes wrong, like I forget something, can't find something or get held up in some way that I run out of daylight before I get to start hunting. If only my mind could figure out it's legal to night hunt in dreams.
I don't think I have ever actually caught a fish or harvested an animal in any dream. I don't think any were actual nightmares, theme is always just a little frustration and disappointment.
One time I had a nightmare while I was asleep at camp. I dreamed I was in some slum getting robbed and screamed at the top of my lungs. Scared the heck out of caddisguy. Thank goodness my brother camped 20 yards away didn't hear because of the loud creek. Probably would have jumped out with a rifle.
