For as long as I can remember I have always had vivid dreams. Colorful, emotional, so intense sometimes I could smell or even feel things. I think it is because I have always had a super active imagination.
Since after the SCA I have had less than normal (for me anyway), and if I do get them they are not as vivid. One that I had shortly after coming home was in black and white. I was watching my own heart beat, this I could feel. I felt my heart speed up and the stop. I saw it all in black and white, there was pain and I woke up. I have not had one like that since then.
Perhaps, this is keeping me from continually living in my own head, forcing me to act on what is happening in the world outside my head.
