Your experiences relate a lot to mine up until 15/16ish. (Life is not entirely different now, it is simply more balanced at 21.) I don't know how old you are. Perhaps I was just less introverted than you and had less distance to balance myself out.
The only difference is when you talk about the waves crashing. I used to do the craziest/wildest/most stomach-churning things at amusement/water parks or in the wilderness just to kick my Se into gear.
I don't think I have ever screamed like a typical girl, and I have had many near-something experiences to warrant it when trying to get the adrenaline rush.
I always feel like I can't activate my Se enough. Like I have really low autonomic arousability or something.

I'm similar to that in a lot of ways... I like to spend a lot of time daydreaming, and I can't seem to stay focused on what I'm doing for very long, as it's like I "take in" a small part of an event, and then I want to lie down and contemplate it.
Although one weird trait I have is that I can't stand total silence or darkness. I need to have the TV or radio going in the environment sort of quietly, since otherwise I actually hear things from my imagination, and I start getting freaked out. I also need light, however it musn't have radiance enough to hurt my eyes if I open them. So I don't want too much stimulation, yet I also can't cope with none at all... I must have things just so in the environment in terms of noise level and light for my own equanimity so that I can sleep (interestingly, messiness doesn't make as much of a difference).
EDIT: Well, thanks a lot for making me reply for nothing. I actually put a lot of thought into this post. Oh, I understand... that I'll have more reticence responding to posts of yours in the future without worrying that you'll just delete them, and then I'll have wasted my time/energy. No thanks, I think I'll stick to replying threads that don't disappear, if it's all the same to you.
EDIT2: Sorry, I know you didn't plan it this way... sometimes I take things very personally.
