Granted! You can choose your own bane:
A) All of your senses are now focused towards the internal rather than the external: you can see your insides, you can smell your insides, you can feel your insides, you can taste your insides, you can hear your insides: but you can't see anything outside of your body, you can't hear sounds that you didn't produce, you can't smell odours not emanating from your body, you can't feel anything on the external side of your skin. You can follow your entire digestive process: see, smell, feel and taste your food becoming turd
B ) becoming an obligate cannibal: you have to eat corpses (you can also eat them bite by bite while they're still alive, if you want). You don't necessarily have to kill someone to feast on their flesh, blood and marrow: an already dead person also works! This is the only way you can get nutrients and satiate your hunger, you can't even stomach any other food. Your hunger pangs are worsened to become thrice as bad. Oh and you still feel hungry around three times a day. You don't get any enhanced vampire or ghoul abilities to go with, you're still just a normie... eh, sort of. See, you're more like a zombie and you'll get worse the longer you go without eating. You'll slowly start to loose any sense of self, any joy, any loss, those day-to-day annoyances. The only way you can continue to feel is to experience the lives of those you ate. Then you'll feel alive again
C) You have to earn every hour of your day here on this Earth. Twice over. For every hour you experience living your life, you have to spend two hours in complete sensory deprivation. In a state where you are somehow completely aware and awake but without a body. You exist but there's nothing: not in the sense of darkness but in the sense of that thing at the edge of your vision, you know? Our eyes have a visual range, that means we can only see things within a certain visual field, beyond that angle... it isn't darkness... it just isn't anything. That's what you... "see". That and a true silence. And absolutely no part of your body touching anything, feeling anything, since you don't have a body to begin with. Oh and I do mean an hour for two! As in, if you want to experience 3 continuous hours of life, you have to earn it by experiencing 6 continuous hours of nothingness. Another Oh! That time of nothingness is taken off your lifespan.
Choose!
Hmm... What to wish for? Oh! I want a gaydar!
