I had a dream that i was running through many doors in a very big house. I would open all of them with no problem, I cam to one particular door though and i opened it and it was just a big ball orb of light with tendrils of light coming off of it nothing else, no walls nothing just an expanse with this orb floating right in my face. Something possessed me to immediately shut the door though and move on as if it scared me. Later in the dream I was having an affair with an ex friends girlfriend who I really dislike in real life.( dont know if this is just random or not) please help.
