Dream can't really tell you what other people think, they do sometimes hint at it through your own subconscious observations but they usually only reflect what you think and what your subconscious wants you to think.

This doesn't mean that he doesn't like you, he may well do, but you have to be careful sometimes if you think dreams are making real life predictions, they usually aren't. Still, if you really do like someone and your dreams reflect that, you should probably look into it to see if there is anything there.
