Have you ever played a game where you were blindfolded and your playmates will hide and you need to find them? It was one of my favorite game because you can see the person looking for you and you can move every time as long as that person can't catch you. Whenever I was blindfolded I will bruise myself bumping into furniture. I can hear my playmates run around but I could not figure out where they are because their laugh echoes around the room and there are tons of movement all around. I have noticed that I need to listen carefully and when I'm close to someone the temperature changes and the air were different. I can feel breathing loudly and that's when I knew I found a person. Not being able to see was challenging but you just really need to focus on your surrounding the sounds will determine if there are object nearby.
