Well... i do astral projection while sleeping, and even if i couldnt induce a full wake-induced astral projection yet, i can differentiate usual dreams from the astral projections i have when sleeping. And very frequently when i project i notice im in the house i lived my entire childhood... which is, coincidentally, the house where i started to astral project. (I remember several "dreams" i had when as a child that now i recognize were in fact astral projections).
I dont know if it has any relation with what you mentioned... did you started to astral project in that house? Did you had some "unusual" experience there when recovering from psychosis? There must be some answer to it, even if we dont know it yet...
Anyway, i would not worry about it... if you ever die, even if your "spirit" go there, it wont be there for long, so you dont need to worry about being trapped there forever...
(Note that it doesnt mean you shouldnt worry about to where your "spirit" will go when you die, but its another subject...)
