Nothing wrong with wanting to have an afterlife that is of your own making but yes in my explanation the astral is a real place, things created in that place are real within the confines of that plane, it’s their home. I call it the plane of imagination simply because of the vibratory state it’s in where it is very malleable by the imagination of any who go there.
However, when a person “carves out” their own space they are very capable of altering the vibration of that space which I did with my astral temple, but I have a side project I want to create soon that I plan to share on the forum at some point lol.
