Had a dream while we were dtd😳

so me and my boyfriend were dtd last night and he’s on top. we’ve already went one round so i know it’s harder for him to finish the second time. well his face looked like he was about to explode, and i ask him if he’s going to finish and he says no. so we just completely stop. he lays down beside me and i say “you look like you were about to finish, what happened” and he says “i felt it coming on and then i had like a mini dream” my mouth opens and i’m super confused at this point. i asked him what his “dream” was about and he says it was me and him laying in his living room floor just hanging out in the future. so he lost the feeling of about to finish because he thought about our future ... i’m so confused and i believe he was thinking about someone else or i don’t know what... what do you ladies think ?
