1st person is easier in that - you think of what if and put yourself in the character shoes.
- What if a dinosaur came and just bit your arm and threw you into a intergalactic void dimension that's known for space piranhas?
- What if you just realized your gf/bf walked away with another man in their arms, and you just realized you got cheated on?
- -What if something you feared just happened and its as shit real as it gets and you can't seem to see yourself out of this mess?
Describe how you feel now.
If you always think worst case scenarios, well that's a big boost in creating first POVs. jk lol. On the bright side, it be like all those scenarios you daydreamed that your crush actually likes you back like some YA novels. Now you just describe it lol.
The second part is blurring other voices that are not your main op's voice. Irl, you know your thoughts, but you can't read others thoughts. Similarly, character in 1st POV can narrate/speak/understand their thoughts, but may not understand every action/thought of another character.
Unless its purposely wired into the story in some way, like ex: special mind-reading ability or genius. Just don't go too overboard with those abilities though.
- A dino just attacked a group of shoppers. You aren't really focusing on them though, you worry about getting trampled yourself in the chaos.
- Your character is expressing how it feels to see them walking away. Not thinking from the pov of those darn two who plan on a little evening fun.
- Your character just been through some shit/got some shit news. People and their voices blur in the background as character focuses on the shit.
