A Warning Vision

When I was in grade school, my friends and I are heading to the basketball court and saw a mango tree right in front of a house. It bears a lot of fruits and most of them are already ripe. My friends wanted for us to get some, but I suggested it will be better to ask permission from the owner first. We knocked on the door and called out, but there's no answer. Thinking that nobody's home, we climb the tree and help ourselves with some of its fruit. 

We're still on the tree while we eat when suddenly, an image pops up into my head warning me that there's some kind of  a ''monster'' behind us. I had this impulse to jump out of a tree and without second thoughts, I did. Afterward, I quickly turn around and saw an old man with a thin, long bamboo stick hitting them. They too immediately jump out of the tree. We ran until we reached the court. Still catching our breath, they asked me why I didn't tell them that the old man is coming. I said I didn't know. They wondered why I jumped out of the tree in the first place. I explained to them the reason why but they don't know whether to believe me or not. They didn't ask any more questions after that. They just have this puzzled look on their face.
