When seaweed grazes your feet or legs in the ocean:
"Guess I'm dying now."
Trying to put on clean clothes after a shower in a hot and humid room.
Randomly crunching down on a couple of grains of sand.
Stepping on a wet floor while wearing socks.
Bed spins after drinking too much. Walking through an unseen spider web. That feeling you get when you suddenly realize that you left your purse/wallet/phone in a public establishment..over an hour ago!
