This Dream:He's not my boyfriend!

Alright, I'm new. Just thought anyone would like to know. I woke up an hour early today, and I noticed that there was a weird , sort of "after taste" of my dream that I never really experience except for every once in a while. so I decided to write it this time, and i went to a forum to maybe find out what it means.
Ok well I only remember the last bit of it, I don't know what happened in the beginning of the dream.

Well, i remember that i was being driven around in my boyfriend's neighborhood by my grandmother. We came up to his house, and i looked into the window. My grandmother asked me if he was home, and i said yes, and that i saw him with some girl.

-Now let me say, that now that i recall in my dream, that was NOT my boyfriend. That was this guy that i know from around town. We really don't like each other that much. He ignores me existence and i think he partys and dates too much. But thats only my opinion of him, i dont think of him, ever really unless im around him. I have absolutely no attraction to him whatsoever. I dont think i would ever consider dating him. -

But in my dream i never denied that he was my boyfriend. Now, when i looked into the window and saw him, I noticed that, yes it was my boyfriends house, but it definately was not my boyfriends room, as the walls were white when they are usually blue and the bed was facing the window when it is usually facing the wall. The guy and some girl were sitting on the bed at opposite ends, staring out of the window at something. I have no clue what they were looking at.

Then my grandmother asked me, "isn't he always with some girl?" and i nodded for some reason and she drives away. This is where it gets weird. She starts going the wrong direction out of the neighborhood, like she has done many times before. I told her this, and she looked around and started turning in the right direction.

Then she looks over at me and says, "Well be careful, because remember there is a man on the loose who is eating young girls like you." and right after she said this, my alarm went off, and i woke up.

I want to know what this means, it was really strange and though, non-lucid, i think that it has a meaning all the same. :shock:

last night i dreamed that i was on some sort of a steam boat or something other, and my family was there. (surprisingly no bf) and the they were cleaning something out i don't remember, and a drop door fell open and there were spiders and worms and leeches on the deck. i remember that we were supposed to be cleaning them up and i saw my dad and then i looked at a wall and i saw two light green spiders and then i saw my face in the window, but i looked like a ghost or something, and my face was un-natuarally thin. then i woke up.
