So I do know some astral techniques of invisibility, you can call it stealth mode or ghost mode. So to change your astral energy (or physical energy ) signature you just learn to shapeshift into something else, or let another version, incarnation of yourself possess you. And wala! anyone looking for your energy signature will probably not be able to find you if they are specifically scanning for the old you. You could also make a sigil or pendent and wear it which gives an automatic compulsion command like “everyone will ignore my existence”. You can even just think that constantly in the astrals and be invisible in a way; you can even just say “everyone will forget my existence” and keep that compulsion command up and you can probably go anywhere you want too.
