<human>: Can you provide a brief rundown of the text in within 3 sentences?

I (23F) have been having night dating my boyfriend (25M) for about 6 months now. Before that we had become best friends over the course of 4 months. After constantly flirting he finally made a move, and now I couldn't be happier. I realize that it's still early in the relationship, but everything feels very real. 

Every night I fall asleep thinking about how happy he makes me and how much I love him (I can't even help thinking about it). But several times now, I've had extremely realistic nightmares about him hitting on other women, cheating on me, etc. Things that make me lose my trust and feel heart-broken. Everything feels real and it makes me wake up tired and emotionally drained. 

I have absolutely no reason not to trust him. We are super open with each other about everything, even if that means having uncomfortable talks to work through issues. He isn't the flirty type in general, and we spend most of our free time together.

My last boyfriend sort of blind-sided me with things that made me lose his trust (in real life), and I'm worried that my brain is just being paranoid because of that situation, even though it was over a year ago and I have worked through the issues as best one could. This is the only possible reason I can think of for my dreams.

I don't want to feel this way but how can I control my dreams? I've told my boyfriend about them and every time he comforts me and makes me feel better, but the frequency and the realness of them is starting to get to me. 

Any suggestions of what I can do?
<bot>: ! : I (23F) am having re-occurring nightmares that my boyfriend (25M) has been flirting/cheating on me when my awake brain trusts him 100%. Help?
