Dreams

I wonder if dreams are a sign of something great to come pregnancy dreams the SO is dreaming them not me .. But bf jumps up in the middle of the night scaring the crap out of me he walks to the dresser reaching like he's picking something up but grabs nothing than goes to the other side of the room , I'm use to him talking in his sleep some nights but he's never been a sleepwalker until lastnight. I asked him what is he doing what's wrong he's like I'm trying to put the baby back to sleep 😲 stood there for 2 minutes or so cradling his dream baby than back in the bed still sleep not gone lie I was scared as shit I slid all the way over to the far side of the bed 😥 lightly sleep. Got up this morning told him what happened an what he did he don't believe me or remember me talking to him but he told me he dreamt about a baby being around the house he don't remember the whole dream he give me little snippets of what all he remembered kind of explained why he was doing all of that .. We're not ttc we kind of rather it happens unexpectedly not planned to stressful. But I'm just wondering does dreams have messages and meanings ig
