3: These are decently scary.
5: Isn’t it the same as being afraid of aquariums?
6: What’s going on in the third picture?
11: >>6 Isn’t it the ocean current?
7: That third one is amazing.
9: Even when you understand the principle of them, spillways are terrifying.
10: Is the third one the edge of the world?
12: The third one isn’t scary. You’ll probably die if you get sucked into an ebb tide, right?
13: The third one is Mauritius, isn’t it? The way you see the ocean floor and the currents give the illusion that you’re falling.
17:
31: >>17 Don’t hide it.
39: >>17 Thank goodness, it was a peaceful photo in the end.
18: The second and third photos are scary. The first, not so much.

20: I find the second photo the weirdest. I wonder why?

23: Tokyo Bay is scary.
24: Wouldn’t a spillway that is clearly man-made be more scary?
27: >>24 I get it. You start thinking like… what if I fall in?
28: >>24 That’s a no from me.
29: >>24 It’s like a gateway to an undersea route in a game.
34: >>24 Why are people scared of this? I’d love to see it.
47: >>34 Because it makes you imagine falling in.
32:
45: >>32 Personally I think this is the scariest.
67: >>32 This is pretty common in The Outer Worlds.
41: That picture of the overturned boat in a downpour with a huge monster beneath it is scary.
43: >>41 Yeah those are terrifying.
51: >>41
52: This scares me to death.
55: >>52 It’s like Beksiński.
58: >>52 Images like this are thrilling. Like this videos of whales emerging beside small boats, they’re terrifying.
54: It’s scarier without water.
70: >>54 It’s like a Shinichi Hoshi work.

61: The parts of the Pacific Ocean with nothing there are terrifying.
68: >>61 You can see it on maps, right? I get it. It’s just nothing but blue.

75: The world’s deepest pool.
64: It’s scary. I hate it. I don’t think I could deal with space either.
