Yes on two occasions now.

But they are in a different dimension I think, they came to me and done some kind of energy work on my forehead and abdomen I got the feeling it was a form of protection, they looked like they were made out of mist but human looking like us.

If I concentrate on them they show up I also just get a "feeling" when they are near.

It used to freak me out but hey I'm still here so have started to embrace it.
