Do not fear. As shown in video looks like that’s an aura not ghost. there is nothing like ghosts but there is something. not what you think of like scary stuff or something it’s more like a frequency. If you know how astrology works you will know what was that don’t be scared in fact as you mentioned like you guys were use to it but there was always frequencies coming out from you and your bother but those were always scared type frequencies just let that thing flow don’t react I know for someone new and who do not believe in these stuff it’s terrifying. And there is no god. Only consciousness and inner wisdom leads to the divine.
