I had conscious experiences with Greys starting December 21 and 23 of 2007. I only remember the beginnings or ends of the visitations, never the middle.

I had many visits between end of 2007-2010. Once I got over my fear of the Greys, then the mantis type came, and the Greys never came back.

Greys come in groups of 4, with one taller than the others.
Mantis comes solo.

Mantis has a very matriarchal energy. Sometimes even timid.
