Stargate skills

1. Perceiving and witnessing other person's or ALF "precognition" astral body;-
seeing a "grayish/brownish" quantum type energy body, is sometimes an indicator of a person's intention to arrive at a destination. They may be scouting the area ahead of their entry.
These apparition-like energy fields could easily be confused with another paranormal entity or ALF. However even ALF have ability to quantum scout/ aka astral plane. It is just that the focus of this more routine matter for them may startle the newcomer watcher.
