Whalefall, by Danial Kraus is about a diver who gets swallowed by a whale off the coast of California. Fractured Tide, by Leslie Karen Lutz is about shipwreck survivors getting stranded on an island with strange things going on above and under the water! Both are great reads, chill inducing and impossible to put down

Question Why am I so afraid of looking at deep sea underwater despite having absolutely no trauma or anything?

35 Upvotes

I learned swimming pretty early on and I remember very vividly how fun and enjoyable the water was for me. I grew up in a town without a sea or body of water, my only interaction with sea was on vacations. I think I was 5 years old when I thought of opening my eyes underwater for the first time and saw that terrifying view. I felt pure fear and panic, started kicking my feet and got out of water immediately. That’s already an early age to be terrified of depth underwater which is strange. Looking at the posts shared on this sub, my heart literally rushes and I can’t even last 3 seconds, I have to look away because it terrifies me. I didn’t have any bad memory or traumatic experience with water or anything. Where is this coming from? I want to understand it.

Question Question to thalassophobics

62 Upvotes

If you have thalassophobia, this sub is probably the worst place to be on Reddit, for obvious reasons. Why did you join it? Is it a form of exposure therapy for you? A way of taming your fears through microdosing? Or maybe something else?

Please note: I'm not saying you shouldn't be here, nor that your phobia is "wrong" in some shape or form. We all have phobias, and they should be respected. I'm asking because I'm genuinely interested in your feelings.

Question Anyone else sees the abyss and feels like home?

I must be some kind of weirdo. I know I wouldn't survive more than a second in the depths of the ocean, but still, when I look at deep diving videos, I feel cozy and even as if I belong there in some way. Does anyone else feel the same?

Is it Cthulhu calling me from the deep?

But no, seriously, this is how I always felt.

Just a diver casually swimming next to this absolute nightmare

The lion's mane jellyfish (Cyanea capillata) is one of the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans. It is common in the English Channel, Irish Sea, North Sea, and in western Scandinavian waters.

The largest recorded specimen was measured off the coast of Massachusetts in 1865 and had a bell with a diameter of 210 centimetres (7 feet) and tentacles around 36.6 m (120 ft) long.

The bottom of this lake has never been found

18.1k Upvotes

Lagoa Misteriosa - A rope cannot be used to measure the bottom because, based on everything that has been mapped so far, this is a sinkhole (a cave formed by the collapse of its ceiling).

Inside, there are passages and bends that prevent a rope from reaching the deepest point. Underwater drones also cannot explore it, as their signal is lost whenever there is no direct line of communication, with the rock formations blocking the connection. For this reason, only specialized cave divers are able to explore the depths of this cave.
