Was It All A Dream????

Last night (actually early this morning) I was sitting at my computer doing some stuff on myspace, the next thing that I remember was my lil' (younger) brother saying "YO" to me on google talk. Since it was so late I was like what the heck??? So then I heard my cat in the hall way, I heard this ball that makes a crinkling noise when he plays with it. Then I remember going out into the hallway where Buster (my kitty) was and picking him up , then I took him and laid down in the bed. The next thing that I remember was Buster biting down on my finger, and I was trying to pull it out of his mouth, and he would not let go. I am wondering if this was all a dream. The first reason that I think that I was dreaming was because my brother would never be up on the computer that late, and another reason is because Buster would never bite me so hard , to the point where he would not allow me to remove my finger from his mouth. I just don't know what happened, and it's really freaking me out. I could understand if I was out drinking or something all night, but I wasn't....I was stone sober, so the only conclusion that I could come to is that I fell asleep at my computer and had a little dream, and that's why I thought that my brother was talking to me on google (because I was trying to get in touch with him all day on there). So I guess that it was a dream after all, but it was really strange, and I am really mind boggled over all of this, oh well till next time.
