Dream About Building Coffee Table

I was in my apartment to building my coffee table. But there were no windows or doors. All my other furniture except my sofa has disappeared too. I'd made a few mistakes while building the table so was taking it apart to fix them. And my ex kept popping in and out the room. Watching me while I was rebuilding the table, laughing and joking at my mistakes like we always did. Eventually he told me to hand him the screwdriver so he could fix it. So I gave him the screwdriver and he put the table back together perfectly, fixing all my mistakes. He then stood up and cuddled me as we looked at the table proud of what we had made. I then remembered we are broken up and felt an overwhelming sense of sadness. I knew I'd never actually experience this moment in real life and it was all a dream. He had disappeared from my arms. I hasn't even felt him leave he was just gone. And I stood staring at the table feeling this sadness.
