Claims of being a famous person in a past life

Somebody said there's a huge following of reincarnation claimants on Instagram, many of whom claim they were a famous person in a previous life. I think it's highly unlikely that a claimed past life of a famous person is genuine (even though I think at least some people reincarnate).

What percentage of the population were represented by famous people at the time of the claimed past life? Very small I imagine. I'd put my money on none, or virtually none, of these claimed lives as being for real. People crave the attention, and others duly oblige.

In my other blog I have a series of posts addressing criticisms of reincarnation. Part 1 is here.
