As kids we used to walk around the house looking at a hand held mirror pointing up to make it seem we were walking on the ceiling. Our house ceiling had exposed logs, vigas. So we had to step over them. Most of the time we'd trip over chairs or tables and just laugh.
Try it, it's a little juvenile, but we found it fun until we broke Mom's "best" mirror.
Loved it! All of us can relate to this, especially those of us who were abused in childhood.
In California, we did a lot of swimming, and the chlorine from the pools would irritate my sinuses. I used to take nose drops, a lot, and had to lie on the bed with my head down, for several minutes, so the medicine could work--so I was very familiar with that upside-down world.
