Yes, anybody that wishes to believe in superstitions can.
Because nearly all of them are unproven.
People believe in superstitions because they are driven by fear.
Possibly because they were religious. People who are not religious do not normally believe in superstitions.
I do not believe they are true.
Superstitions are beliefs supported only by rumor, not by factual observation. Rational people therefore do not believe such things.
It has no survival value. People believe in in all kinds of things which others would consider superstitions. In most cases it does no harm.
The month of Safar is like other months of the year. The superstitions associated with this month are totally baseless. Islam does not believe in superstitions.
They don't really. People who believe in superstitions are more prone to believe in the haunted houses thing than people who don't.
No, superstitions are an adjunct to religion; if you rid yourself of religion you also rid yourself of superstition.
Superstitions should not be believed simply because they are not true at all. Some are totally fake while others are coincidental at best
