Cities in the Astral

Took a wrong turn I guess and found myself in the realm Hindu call the realm of hungry ghosts. It could have been terrifying as it was like vampire demons wanting to eat me. I calmed myself and extended a barrier around me, sort of like starship shields on movies. I calmly did mudras to bring intense focus, then started proclaiming I was a servant of the Good and the Light and that they could not touch me. this enraged them, but they in fact could not touch me. I left that realm swiftly.
