This is a drawing of something from a dream I had.
In this dream there was a beach that grew giant fruit (on the left of the sign). These fruit were big and nutritous so people would harvest them and sell them. However, these fruits grew next to a part of the ocean with dangerous chemicals in it. When the sun shone through the water onto the fruit the fruit would become toxic. It would turn bright pink and green and if someone touched it, it would explode and spray orange-brown stuff that burned anything it touched. So this sign warned about that. But it just confused people.
