Dreams, what could this mean?

I will explain to you the reason why you should not trust dreams. Dreams are nothing more then memories being sorted out in your mind into 2 sections "relevant (remember this memory)" or "not relevant (forget that memory)". Once you go to sleep the images get put into a strange order as follows: It goes into your temporary memory like this (Memory 1 (you see a person) -> 2 (you see a camel) -> 3 (remember other things for the other numbers) -> 4 -> 5. But when you go to sleep it gets all messed up the whole order is just ignored so the memory's get put in a strange order. for example with the boy on memory 1 and the camel on memory 2 although you might have seen them completely separate during the day the boy could be sitting on the camel in your dream because the mind messes up the order of which information gets stored (the 1 -> 2 -> 3 -> 4 -> 5 could become 5 -> 2 -> 3 -> 1 -> 4). If you dream about people or something it does not mean anything it's just a stream of memory's flashing trough your mind in a wrong order which can cause even the weirdest dreams.

BUT (exception)

Not EVERYTHING in the dreams have to have happened on the same day. If someone is suffering from strange nightmares it's usually because in the past if they had a bad memory and the memory gets recalled and processed by the brain during the sleep which can cause the bad dream.

I hope I cleared stuff a bit up for you (about dreams)

Umm this could mean that you have some doubts about him. Maybe you are just scared of this actually happening. Whatever the reason don't worry to much.

Maybe you like him, but don't exactly want him to know that you like him. It could be your hidden desire to avoid him, so that he doesn't know your feelings.

I don't know much about dreams, but my aunt told me that they represent our feelings in some way (she took a class about dreams a few years ago). The fact that this guy got arrested for drunk driving and ended up at your house where you ignored him could mean that you hope he didn't catch you driving by his house earlier.
