Dream About Ninja Course And Strange Disease

My dream was about one day I was on a ninja course a little one that kids play one I was almost to the finsh line when I was stopped by a girl that said do not go there people are trying to take kids so I ran out of there and told my dad he said that is true and everyone is acting weird there was this sort of disease you can say that was making people acting strange and weird mostly adults they look like them selfs but come of creepy and a new personality causing some of them to go insane like banging there head on a table and eating cereal at 3:00am to taking children this affected everyone expect me my dad and my aunt
