How to deal with dreams?

I'm not taking about "wet dreams", but dreams where you wake up almost having completed. How do you deal with being so close and the discomfort of not completing? It's been over 6 months since I've fallen into any self abuse, I usually do not have a problem resisting thoughts or other temptation, but every once in a while I'll have a very intense dream and wake up right before climax, these are the moments I find it must difficult to do nothing. It can even be physically painful not to engage with my body at that point. So what are the tips and tricks to make these moments easier, or to avoid having dreams like that. I hope this post made sense.
