I am not sure if this falls under the heading shadow spirits.

I was asleep--unconscious--when suddenly I became aware of a black figure. It said one word. I also saw the word spelled or I would not have known that it contained a silent 'h'.

It was over in seconds it seemed. I woke up with my heart racing although I do not remember being afraid.

I googled the word. It was a Czechoslovakian word meaning tear, the kind that flows from the eyes.

To this day I have wondered what it meant and why a black figure.

I came across succubus a long time ago. All I remember is that a succubus desires sexual encounters.

By the way, Sangress, I saw your drawings. They are beautiful, you are beautiful.
For what it is worth.
