But it could also mean he is crushing on you too. I've had many dreams about my ex boyfriend that I care about a lot. I have had many dreams that we were spending time together. The next day he ends up talking to me randomly and we hangout. I had a dream that he told me he loves me. The next night we had a long talk about us and he said those three words "I love you" for the first time in months. I do think of him and my feelings for him a lot, but I think he thinks of me and my feelings for him about the same. Because every time I dream of him he will pop back into my life. They say when you dream about someone that means they were thinking of you. I believe that.
Also when you dream about someone it is because you have some kind of connection to that person. In your case you like him, so that could be why you dream of him.
But I think there is a possibility he likes you back.
