Recently I've noticed I've become helluva paranoid when in the pool. This gets worse when I'm alone and I think up all sorts of strange things and actually completely believe they may happen. If you've watched Interstellar you may recall a scene on Miller's planet with the huge waves, and I (for who-knows-why) thought that I would die from a tsunami in my own pool. This morning the cleaners were doing their weekly drainage at the children's pool and they've dropped in the floating beacons in my regular one, and for some reason again I was convinced I would die in a whirlpool formed from the draining. Another one I can remember is the constant fear of there being some creature lurking beneath the surface such that I don't dare to swim or get out because apparently movement attracts its attention. I've also felt like things such as passing planes overhead or cats scampering about are messages/warnings to be decoded that is crucial to my survival.

Do I have an overactive imagination or what? I have been swimming from age 3 so why am I like that all of a sudden? I hate being so petrified while in the water that I don't even dare to move
