I’m with you. There is something to apparitions. I don’t know what it is, but there have been too many credible accounts from too many sober minded witnesses for thousands of years for there to be “no there there.”
I’ve had a few occasions myself. My religious belief tells me that there is no such thing yet there they were. Either demons or some sort of echo or shadow from the past. No attempt to manipulate or even awareness that I could see, so over time I’ve concluded that I was actually seeing a glimpse of the past.
