There seem to be quite a lot of great knowledge about your spirit guides and how to fight these entities that drain you. It seems odd that someone would attack you and at the same time tell you how to defeat them. So have you ever thought that this knowledge you gained was from your guides to prepare you for a nearby attack from these entities or help you defend one that was already taking place. And the reason why they communicated with you through telepathy was because all other lines were being blocked by these entities.
