>The fucked up part is that they can read all of your thoughts, so they know your deepest shit and how exactly to fuck with you and keep you enslaved as a food source.
No they don't. Astral parasites come in two variants: Lesser and Greater. Lesser ones are like beasts feeding on a carcass, they go to wherever food is plentiful. Greater ones actually have some intelligence, but can only infer what will make you fall into temptation based on how your "aura" reacts to emotions and stimulus.
No external entity in this plane/or that manifests in this plane can read minds as it's a breach of free will. Some can influence dreams, opinions and get you to expose your thoughts, but mind reading is beyond the realm of the external.
Men usually have a couple of dozen of astral parasites ingrained on their outmost ethereal body because of our very active sexual nature, most of them will die if starved. A pinch of sulfur in your shoes plus a month of no porn, fantasizing, masturbation will solve for most parasites.
Astral parasites will congregate where powerful energies converge, places of sexual and emotional nature as these are excellent catalysts.
Big vampires usually wont leech individuals since they can achieve more by influencing people to create cults and feed them through other means (orgies, corruption, by use of a symbol etc).
Now stop fear mongering and just keep yourself from doing degenerate shit. Also: Bathe regularly and keep your living space clean and with constant sunlight shining in.
