None.

Even things that appear to be rational deserve a skeptical approach.

None that I know of. However, I'm still open to the idea of ghosts and paranormal. Skeptic, but open-minded.

Still making a list of Filipino superstitions, in the meantime . . .

"When you believe in things that you don't understand
Then you suffer
Superstition ain't the way"

I was raised with lots of them and I find it interesting that there is often a good reason for them. For example, you aren't supposed to put hats on beds because back in the old days people often had lice. Here's a link to explain some of the more common superstitions.

For the record, I don't believe in any of them.

Don't open an umbrella in the house, it's bad luck! Lol that's about the only one and as much as my son opens his in the house I've gotten over it!

as many as I can! rituals are fun! especially those of the satanic persuasion \m/

I work in medical care. Not sure it's completely a superstition, but I firmly believe in the weirdness that goes with a full moon.
