Explanation
In this comic, a couple is lying in bed at night. The woman wakes up and exclaims "Gah!" then confesses to her partner: "I dreamed that I cheated on you with your best friend. I feel terrible." The man responds reasonably: "Oh, don'''t. You can'''t control your dreams, so you shouldn'''t feel bad about it."
The woman then says "Really? That'''s so sweet" -- but the man quickly interrupts with "Shh! If I fall asleep right now I can catch it again!" The joke is that instead of being comforted by his understanding response, we learn his apparent maturity was actually just impatience -- he wants to hurry up and fall back asleep so he can have the same dream himself, presumably because the dream involves his own partner in a sexual scenario he finds appealing.
The votey panel shows the man sleeping peacefully with a thought bubble reading "So... hottt..." -- confirming that he did indeed manage to resume the dream and is thoroughly enjoying it. The comic plays on the common relationship scenario where one partner feels guilty about a dream, but subverts expectations by making the other partner'''s "understanding" response actually be motivated by self-interest rather than genuine empathy.
