Why Ghosts Appear Near Water

Did you guys know this? Apparently, ghosts often appear near bodies of water. The reason is simple: they say it's because they're reminded of being in their mother's womb. If they can't pass on and find peace, they apparently cease to exist entirely. Also, tunnels apparently remind them of their mother's womb, which is why ghosts are often found there. It's said that's also why Jizo statues are sometimes placed near tunnels. I hope to find peace quickly when I die.
