This is basically right, though I'd reserve a special place for unlikely but not paranormal beliefs like Bigfoot and the Loch Ness Monster. Those don't violate any physical laws, and there's nothing irrational about thinking they might exist. Enough supposedly long-extinct creatures have turned up in hunter's traps and fishermen's nets that I wouldn't be shocked to find, say, a relic population of prehistoric primates scraping out a living in the Pacific Northwest.
