I guess nobody can control about what he dreams. Very often the dream is very intense, but after you wake up you forget about it completely. I have had many dreams about people that I haven't seen or thought about in many years. I do have a recurring dream about New London/Groton, Connecticut. To make a very long and painful story short I lived there in 1977-78 and things just didn't work out there and I moved back to Queens. Every so often I dream about looking for an apartment there. Other times I am apply for a job at the company where I worked at that time. The end of the dream is a wake up call. I am just grateful that I am not there.
I thought of a few Bob Dylan songs about dreams, bu they just don't apply here.
