Thanks everyone....I haven't watched any of the video's (just can't stand here for 2-3 hrs), I'm more of a reader, and from what I've seen, it's pretty obvious.
If you needed further confirmation, he created something called CE-5, Close Encounters of the 5th kind, some kind of meditation thing
https://en.wikipedia.org/wiki/Close_encounter
"A close encounter of the fifth kind refers to human-initiated contact with extraterrestrial life forms or advanced interstellar civilizations, claiming direct communication between aliens and humans.[13] Close Encounters of the fifth kind (ce5)
was first coined by Steven M. Greer.[16]
In a CE5 event, individuals or groups use specific protocols to establish communication or interaction with extraterrestrial beings. These protocols primarily involve the use of contact meditation and use of sounds or signals. Close encounters of the fifth kind is also referred to as human initiated close encounter.[17]"
Its guided meditation in order to not only communicate with UFOs, but to summon them, for people to "see" lights in the distance, not to bring them directly to you, but maybe that is behind a massive paywall?
Im not sure if he still does this, but he also had an application for people to use around the world. There is also a new documentary by him called "Contact: The CE-5 Experience", that released this year, but I have not seen any of it.
Considering I do not know what is within the application, it could be malware or data harvester for all I know so I do not feel comfortable linking it, but I believe its called "CE5 Contact" and its easy to find, its an application that is meant to help you meditate and connect with aliens and UFOs.
He also claimed to have a number of images of Astral Aliens, this is one of them that is meant to be some kind of.. Alien astral projection or something I do not know.
Steven Greer is convinced the below images are some kind of astral projection aliens, and that he can summon them with meditation. Sounds like a joke but it isnt.
So your instincts were correct.
