Ghosts/spirits are clearly not real and I think you’re delusional if you even entertain the idea.

Pretty much the title. I’d like to add that many people in my immediate circle believe in spirits/ghosts and yes, I think they’re living in a fantasy land. Every single story I’ve heard about a ghostly encounter could be explained by 10000+ other things. I think anyone with a “believable story” has every reason to act and lie for publicity or fame. I also think the human brain is really powerful and can conjure up just about anything in the right circumstances and people who have “experiences” are just having their brain play tricks on them based on pre-conceived notions.
