Homemade Universes

It has turned out that the only universes in which I could ever feel really comfortable are the ones that I can create myself. But there's still a big problem, about which nothing can be done. These universes are not like a house that one can build himself and then tangibly live in it for years afterward, which I have managed to do. The physical body on which the mental depends is too closely tied to this universe in which everybody else also lives, and despite all the theological dodges and misperceptions, there is absolutely no evidence that changing this setup can result in anything other than entering complete and eternal nothingness.
