What was the weirdest belief you ever personally held?

My brother was convinced that lovebugs were venomous, but I didn’t listen to him on that one. He was walking outside the house in a place that had a lot of lovebugs and he got painfully stung. My theory is that there was a wasp hiding amongst them that had flimsy-looking yet dark black wings like lovebugs do and he got them confused. Looking at Wikipedia I see that some spider wasps look vaguely lovebuggish and I seem to remember other wasps looking that way as well.

My wife as a child believed that all dogs were boys and all cats were girls.

Other than thinking that magical and super abilities could manifest themselves IRL if you trained, studied, or worked hard enough at it, I can’t remember any other real weird stuff I believed from when I was a kid.

Did you read The Wonderful Story of Henry Sugar? I believed that was a true story.

When I was 6, my aunt, who often stayed with us, called out to me, “Archie is on!”

It was after 8 PM, yet I thought it was Archie and the kids from Riverdale. The cartoon. Of course, it was a 2nd season episode of “All in the Family”.

The theme of this thread is supposed to be weird things you believe in, not demonstrably true things you subscribe to. Being able to hex a field goal kicker is every bit as normal as the ‘loser-rays’ I exude every time I watch my home team Lions play. Yes, I can make the Lions lose any time I choose. All I have to do is watch more that 30 seconds of a game (sometimes even less!) and it is virtually certain that the Lions will lose that particular game. If I don’t watch, there’s a fair chance they may win (oftentimes because of some spectacular play that I missed), but if I do watch, well…

I don’t believe in magic, so I figure the strong positive correlation between these two factors is best explained as being caused by reflected sunlight shining back from Saturn.

This is like the ‘cold rays’ that the moon emits. It’s demonstrably observable: clear night, full moon visible - it’s usually cold…

Were you the Ravenous Bugblatter Beast of Traal?

Save that question for when R comes up in Botticelli.

In kindergarten, I believed President Lincoln had freed the sleighs (which I assumed had somehow gotten stuck in the snow), thus saving Christmas.
