Any Veteran Paranormal Investigators Ever Witnessed Objects Violently Thrown?

In all my years investigating, I've never singularly or collectively witnessed any objects being propelled inexplicably. Can anyone reliably validate the existence of the phenomena first hand and made measures to ensure the event wasn't a hoax or staged. I'd appreciate truthful submissions.

I'm one that generally requires witnessing the phenomena first hand to acknowledge the possibility exists.

Please respond if you're a long term investigator and share. Thanks in advance!
