What do these dreams mean?

I few nights ago I had a dream about my ex boyfriend. Somehow we were going to die and he grabbed my hands and told me that I made him the happiest man in the universe. And maybe a few weeks ago, I had a dream where I tried to seduce him but in my gut I felt myself screaming that this was wrong and I shouldn't do this. This is bugging me so much. I know I don't love him anymore, I don't want a relationship with him anymore and we agreed to be friends. But every time I see him in real life I just can't help but feel this awkwardness, we were close when we were together and now it's just awkward because I'm used to us kissing, hugging and all that jazz for the past nearly 4 years, but we can't do those anymore. What's happening?
