A childhood belief about afterlife

I was a very pious good Catholic little girl. So I thought the idea of dying and going to heaven would be very nice.

I envisioned lying in a bed with elaborately carved golden posts at each corner. Then when one died, four angels would appear--one at each post--and would fly the bed right into heaven. I think I got this mixed up with the doctrine of Mary's assumption into heaven, which the Church was proclaiming at the time.
