You’re definitely not crazy. It sounds like you’re exploring into advanced levels of psychic development. I hope you have a good teacher or spiritual mentor. Going into this type of thing without decent training, by yourself, could prove to be reckless and dangerous. Negative entities can disguise themselves as angels, deceased loved ones, etc, to fool you and influence you negatively, or outright attack you. I decided to get training when I was taken advantage of by dark forces disguising themselves and my deceased grandmother with whom I was very close. Through thorough metaphysical training, I was able to see the truth regarding entities and my deceased loved ones and more importantly control what came into my life and my personal space.
