All this paranoia is connected with the fact that someone attacks you in the astral, or frightens because you go to the astral in the lower body of the cast.
From each chakra a man has a mirage to emerge his subtle body. And from the two lower ones comes a double, which is connected to the world of spirits, demons and other impiety.
If you leave already from manipura and anahata. , then this is no longer.
It follows that in order to master the technique of traveling in the astral you need to develop your energy and open higher chakras and to move your consciousness into a higher double than the level of an ordinary person. This can be done with the help of yoga, esoteric Buddhism, tantra, etc. These teachings are called Poa. There are meditations specifically aimed at this.
But on this path you need a real master. Self-employment is fraught with unpleasant consequences.
