You have to read books about Cayce to understand him. He saw spirits regularly, and even played with them in his backyard. He actively communicated with them, not saw them through some timeskip/warp/whatever.
So did my neighbor. Most of the time she was a functioning schizophrenic. Then one night she walked into our house carrying a butcher knife.
My mother put us kids in the bedroom, told us to lock the door and not open it no matter what until she said it was okay.
When you have real experience with people who see and hear shit that isn't there, it's not romantic or cool. It's sad to see them falter through life, or maddening to see someone use the claim to perpetuate fraud on the gullible.
If Cayce had been scientifically verifiable the researchers who proved it would be as famous as the Ghostbusters right now. And you would see universities offering courses, and kids being recruited to join the PsiCorps straight out of school.
