What are some ridiculous fact you find about ghost?

For those who don’t believe in ghost must have their own reason why they don’t believe in ghost(most are fact). Is anyone here find any ridiculous fact about what they called as “ghost”?

What I find ridiculous fact in ghost is that most(maybe all) of them appear with clothes,in other word it suggest that there are cotton plants(and other fabric producing creature) in “another world” and ghost people who design ghost clothes.

Aside from revived dead cells what are some interesting-ridiculous fact you found about ghost? This could be historically,your experience,personal knowledge,or anything you like to describe.
