The most recent involved a commercial-residential district near the University of Richmond -- altered nearly beyond recognition, but I "knew" the area
Odd how in dreams there are often places and or people who have been radically altered from the way they appear in real life, yet we know in the dream where/who they are supposed to be.
One recurring theme in my dream (besides the "looking for a place to pee" theme already mentioned above) is that I need to yell and cannot.
The earliest dream I recall like this I can recall was when I was in kindergarten. In the dream, I was following my older brother and his friend as they played out in our yard. They were not happy about it (this was a common occurance in real life at the time). They tricked me into playing cowboys and indians, with me as the cowboy (I can still picture the cowboy hat I wore, one I really owned at the time). They, playing the part of Indians, tied me to the stake, which was a metal fence post which was imbedded in concrete along the side of our house (again, something which really existed).
After tying me to the post, they simply walked away laughing. I was furious, and tried to yell at them to come back, but I could barely make a sound. I tried to yell for someone in the house to come out and untie me, but again, I couldn't.
To this day I can recall the anger and frustration I felt at not being able to yell when I needed to.
I have a few dreams a year where this happens. Most recently was a dream in which I was arguing with my ex-wife. I got so furious that I wanted to yell at the top of my lungs, but I could barely make a sound.
I've read this isn't uncommon. The dreamer isn't just trying to yell in the dream, but in real life. Since the muscles involved in speaking are too relaxed to move like they would need to in order to yell, this translates into the dream as not being able to yell while awake (in the dream).
Sometimes I am tryingf to yell in anger in the dream, sometimes I'm trying to yell to warn someone of some danger. It's always very frustrating.
Perhaps it is related in some way to sleep paralysis?
