Its hard for us mortal man to envision the massiveness of Heaven. You will not feel contained, I can assure you.
I never read of any such visits where the visitors felt at all contained.
The expansiveness of Heaven is frequently mentioned.
Methinks your assumptions are flawed.
As a psychologist who’s listened to thousands of hours of narration about personal life experiences . . .
the visitation narratives do NOT sound contrived to me, at all.
Certainly you can claim to be a better psychologist than I am.
