Wow, as big as your sofa! That's pretty big for a head. You are having quite a bit of activity, or I should say, perception. I still think that the darkness, because it activates our peripheral vision (rod receptors), makes it more likely to see "things".

For me it is getting to the point that if I want to experience seeing what is there in spirit when I wake during the night in a highly relaxed state, I need only open my eyes. If I don't want to see, and sometimes I really don't, then I just don't open my eyes. It's not that I think for a moment that anything can hurt me. It is just that so much unfamiliarity for my consciousness can be overwhelming, which translates sometimes to fright. I mean, one time I woke and opened my eyes knowing I was laying in bed, but seeing that I was somewhere else. Somewhere made up of material and colours that are translatable, but not the same as the physical. Though in some way I knew I had been there before (maybe I am always there as well as here, who knows), it was so foreign to my conscious mind that it frightened me intensely and I let out a little scream that brought me out of it.

So was it smiling at you like, "Hi" or like "yum"
