Mysterious sweets

I'm just walking home from school, nothing special. I passed Charlie's sweet shop, my stomach growled at the thought of eating all those sweets. Should I? well its only one small sweet. "I'll have one lemon sherbet" I said to the man. I tasted nice but it made my tongue tingle. I walked a few more steps until I felt extremely dizzy. My feet were sinking through the ground. "Help!" I screamed It was only a few seconds until I realised I was the only person on the streets. "MUM! ,DAD! ,SOMEBODY!". What kind of world am I living in?
