Spiritual / psychic circles. Anyone been involved?

I was wondering if anyone here had participated in a spiritual circle, whereby using a medium to contact angels?

I ask this question, as I assume it has touched a few people lives, and folk who have been in seperate circles have passed each other in the street, or worked with people, without either of them knowing that both of them had, or discussing it in the open for fear of disbelief and/or ridicule.

It's a shame I think, as a bigger circle circle could move bigger mountains.

I look forward to any replies,
Thanks.

I guess that's a no no then.
Shame
