I don't even know where to begin.
My world is primarily one of sensation. It is probably my biggest focus no matter where I am, what I am doing. There is always something I notice, and sometimes I will get lost in it despite my surroundings and the people I am with. I like pretending that I do literally have my own little bubble, and sometimes I just do what I want when I want to in public, and don't care who sees me or what they think. If I'm bored and out somewhere with people, sometimes I just sit down and play with my fingers, secretly, eyeing everyone around me and studying them, watching their twitches, hearing the noises they make, seeing how they react if I catch my eye. I like to think that every person has a story, which they obviously do, and sometimes I just stare at people, trying to concoct their story in my head. It's quite entertaining.
I'd say also that in terms of stimuli, my world is one that must always have sound. I think this is why I tend to talk to myself a lot, no matter where I am. (recently I was doing it and someone kept asking if I was high, and it was really annoying) Utter silence really bugs me, and I think it may be why I unconsciously start talking to myself whenever I'm alone, just to break the silence. Especially if there are mirrors around, I feel compelled to literally talk to MYSELF. I mean, it's rude when there are two people around and no conversation! My world is about appreciating colors and shapes, sometimes just continually tracing a balloon's curves and imagining all the atoms of nitrogen and oxygen bouncing around beneath its surface. I'm a very slow eater (most of the time) because I love the taste of food, I love noticing where the flavor is most poignant on my tongue because of the appropriate taste buds, and I loooove that feeling of not having drunk something in a while and when you do again you can feel it traveling down your esophagus and to your core. It tickles me.
My world is quite literally all in my head, and only does it sometimes leak out when I am talking to myself or with someone, and I feel comfortable enough to share it with them. My world is basically one where I would love to just exist and feel what I want to feel, not worried about what other people may think or react, and to just relate to more people more casually without them being like "Uh, what the hell are you doing? Weirdo." I think that people are too uptight just because they're expected to be, like they have to initially react upset or whatever to things that aren't normal and are possibly outlandish. I wish that people would just do more of the things that make them feel good, and take pleasure in the little things! Like just taking the time to lay out on the lawn and feel the sun heat your face, staring at the bright big blue sky, or laying on a beach at night and feeling the cool sand sprinkle on and off your skin from my your own doing, the water's breeze washing over you with the slightest hint of a spray. Sometimes I wish I were an animal so I could only worry about myself, and just run through the world as I pleased, experiencing what I wanted, being dirty when I wanted to be, clean otherwise, and just feeling everything around me all at once without another care in the world.
