I think I'm generally a pretty rational person, but on the other hand, I 100% believe in some totally irrational things...
Like for example, I honestly believe you can jinx yourself by expecting and
especially by saying out loud some good thing will happen to you. And then if someone does "tempt their luck" by saying these things out loud I try to counteract the bad juju by "knocking on wood".
What about you? Are you also a little nuts?
