I got a dream of going color blind.
The story goes as follows.
There are two match boxes. One is black and the other one is white. The black one is harmless whereas the white one is harmful. Whenever a person lit a matchstick from white matchbox and see the fire, the person goes color blind for 15 to 20 mins. After that the person will slowly get back the original sight starting from hues to eastman color to normal human sight.It felt like real. I went color blind for some time and got my normal sight back. It was a great experience knowing how color blind people see the world.
