If you are ever in contact with an unfamiliar being, particularly from what you suspect may be a different 'dimension' (alternative frequency) and you'd like to determine their intentions ask these three questions. It is universal law that they cannot answer them dishonestly. Ask these questions and look them straight in the eye for their response.
Are you of the Light?
Are you here with my best interest in mind?
Are you from where you say you're from?
