Last year I composed a post about common dream themes.
There are a few more I could add.
One is that we are shopping for and/or moving to a new house. As dreams go, there are always weird complications involved, either with the selection/purchase of the house, or the poor construction/layout of the new house, or the inability to find things after moving in. My past experiences also blend in one way or another. Even though in real life I can't fathom ever moving again, this doesn't seem an obstacle in the dreams.
Another is that I am called to serve another term in my mission in Germany. This used to be a lot more common in the past.
I sometimes dream that I'm in a passenger jet that is on the verge of crashing. We lose altitude and struggle to find a place we can land safely. Oddly (and fortunately) the crashes have never been bad nor caused injury. Flying from Dubai to Frankfurt last month on a red-eye I was dozing off and having one of those dreams.
After moving from my first job at Naval Weapons Center in California to HP in Boise, I often had dreams of going back, or of them contacting me to help solve work problems. They were strong dreams. I had similar ones after moving to Oregon, but not as much.
One dream theme I'm thankful I don't have is one that a SWAT team member shared with the YM at their activity last night. He related an account of how his team was called to a hostage situation and they ended up shooting and killing the suspect (he came out of the house firing his gun at them). After this experience he has had nightmares of someone burglarizing his home, or shooting at him, and it is the guy they shot. He wakes up like in the movies, bolt upright in a cold sweat.
Why are dreams so weird, though? A strange mix of reality and bizarreness.
