There were a lot of different species there besides humans, giants, some that had human traits, some that looked like some of the demons I have seen, some were very different like reptilian features.

Some seemed good and some seemed extremely dark.

Angel’s I believe is syncronicities. I just finished listening to a podcast with Linda Multon Howe about this exact thing. At one part she was talking abount huge black buildings with intelligent walls. Very interesting. His guests usually start about a half hour into the show.
