Dear Linda -
It certainly means that he’s on your mind!
One reason why dreams are valuable is because they show us what we’re thinking about - whether we’re aware of it consciously or not!
In this case, if your dreams surprise you, then maybe you’re more attracted to this guy than you previously thought. Take a second look next time you two are together. If you like him as more than a friend, then go for it!
You know what they say: Friendship is the foundation of all good relationships!
