Should I?

About a month ago I had this dream... one I won’t get into details about on here but it was distracting me at school for like a week after I had it... (it was a good dream like a REALLY good one if ya get what I mean 😏) So the day after I had it I told my boyfriend and my best friend I had a dream that was distracting me and my best friend asked a little about it but I said I didn’t wanna get into it, she kinda caught onto it but I tried to steer her away from it... my boyfriend caught on to it too and idk if it was because we were in public or if he just generally wanted to no know... he said he didn’t wanna know... but I really wanna tell him? Like it’s not like we haven’t been heating up for like the past couple of months and i don’t think it’ll have much difference if I tell him? If yes, plz comment how I can bring it up to him??
