Subconscious trying to tell me something?

Kasee
Hey there!
So, my boyfriend & I have been dating for a year & just recently moved into our very own place together. 
Recently, I've been having crazy dreams of him cheating on me directly in front of my face. I don't know why. We've always been an amazing couple. We never fight, we tell each other everything. I've even told him about these dreams & he reassures me that things like that would never happen.
The only thing is, I feel extremely distant lately. We work opposite schedules. I normally work at 4:30 in the morning & then when I get home, I take a nap & by the time I'm waking up from said nap, he's leaving for work and won't be home until I'm already asleep for the night. I don't know what these dreams mean. Maybe I'm just reading too much into them?
