LukeAndersen – It seems you were slightly delirious. At such times the usual barrier between your conscious self and your unconscious self is broken and so such a flood occurs.
At a time when I myself was delirious I was overwhelmed by a chaos of feelings. Then, some years later when I had learnt to explore my unconscious and emptied our the rubbish and pain and fear we keep stored up undealt with, I again was delirious and saw that I was clear and had no fear or feeling of being overwhelmed.
I also think that sometimes in delirium we are also witnessing the distress of our body in the images and feelings met.
It is difficult to control it until we either clear out the fears and distress, or are aware enough of the inner situation to stand as a witness of it. We are all as young children exposed to fears through images, films and the common attitudes and beliefs we are exposed to. As a child we have immense feelings about things and unless there are met still live inside us. Look at the number of people who have nightmares of being attacked by and animal or demons. They are all fears carried into our dream state by fears we have never met. For instance white Americans dream if being attacked by animals a great number of times; Native Americans do not have such dreams, because their culture does not plant such fears in them. It is largely our culture.
