Relationships- I am having recurring dreams about another guy other than my boyfriend what do I do?

I'm having recurring dreams about another guy. I also find that when my boyfriend and I kiss I don't like to kiss him anymore and sort fake it-feel really guilty. He is 30 and I'm 21. I know I need to communicate with him but not sure how to bring up thus type of conversation with him as he might take it the wrong way. Any good advice other than just breaking up with him because that won't solve a problem.
