From the scientific point of view dreams are I guess manifestation of chemical/physical/biological processes in our brain structures.
From the psychological point of view they are manifestation of ideas hidden deep in our subconscious.
Both statements above seem to be true but they represent different approaches.
My dreams are compensation for my everyday life. In my dreams I find myself surrounded by nature or travelling, rambling through hotel rooms, corridors, foyers and so on. I’m not conscious of my age – I guess sometimes I move back to my (or any other) student’s hostel. I meet people and I seem not to have any interpersonal problems.
Sometimes I meet people who died but while I dream I’m not aware of this. My late brother - a few times a year. My school mate – very often. My father – once or twice in my life… I wonder why as I didn’t have any closer relation with them at all when they were alive.
Practically, I don’t have nightmares. Only once or twice I experienced something funny. I had no dream that night (or forgot it as they say) but woke up in the middle of the night with a strange feeling that something evil (but what?) is around.
