Sliding doors

I know you. I have seen you three times already. Twice in a dream. Once when I had a high fever, alone and just moved in a new apartment. You were sitting by the foot of my bed watching me for three days. And I saw you today. Alive. You looked at me as if you knew me as well. And am I curious enough to ask you questions? I guess not because I did not do anything to approach you. And I guess neither do you.
