I've seen plenty of humans hallucinating many things unintentionally. This does not track. Some people believe there's an entity listening when you kneel and talk to yourself, others will swear for their lives they saw aliens, they got abducted, etc.

Memories are known to be made up by our brains, so even events that we witnessed will be distorted when recalled.

So I agree with GP, that response shows a pretty big lack of understanding on how our brains work.
