I guess today was a bit much. I worked for 12hrs and went for a bike ride for 45min after. Once again I saw someone standing on the edge of my vision, just standing, looking at me. When I look, the person is gone. I really don't know how to deal with this. It happens quite often at the moment. Not always the same szenario, but every day or every other day I remember something and it takes me a minute or so to realize whether it really happened or was a dream.
