To start from the beginning.
I've never suffered from any form of abuse, mental or physical, from my dad (or anyone, actually) so I have no past experiences that could lead to this dream. But since I was about 9 or 10 I've had a recurring dream that can start differently but always ends up the same way.
My dad with a knife, razor blade, etc. and will write the word 'mine' on my stomach with it. And when it starts to heal, he retraces it until it finally forms a permanent scar.
Dad and I have always had a great relationship, both before and after the divorce, there's nothing that I can think of in my childhood or now that could attribute to that, but this dream happens once every month or so.
That said, I'll start with the dreams I've been having lately.

The first dream I had of this man was the 'better' of the two. I don't remember him extremely well from the first dream.
I just know that we were in love. I'd never felt that kind of feeling from anyone, ever. It was a genuine, real love. We spent a lot of time together in that dream, I introduced him to my family, we spent time alone walking around in the forest. Nothing awkward or weird in any way, just enjoying each others presence.
I felt 'odd' for a few days after that dream, too. Like in some way it was real and it happened and I was feeling the effects.

The second dream with him was much more vivid. We were together again but it was a much different atmosphere, nothing ominous but definitely tense in some way. Because of the first dream I talked about, I've always had insecurities of my stomach region. I don't like people looking at it, I don't like exposing it, and I definitely don't like people touching my stomach. And in the dream, he went to put his arm around me and put his hand on my stomach and I didn't make a scene but of course I just really pulled away. And I guess that was the last straw? And he made me completely strip. He didn't physically force me or hover over me until I did, but it was one of those tones that made me feel like I needed to listen. So next thing, I'm completely naked, and he makes me sleep with him. In the literal term, there was no cuddling or advances or any of that, he just made me completely strip before I got in bed for the night. I laid awake all night while he was sleeping and some time through the night he just wound up close and when he turned over, he laid his arm across my stomach and I mentally freaked out. I remember my stomach clenching and I just felt like I was holding my breath the whole time until I fell asleep finally.
When I woke up, he was already up. So I got dressed and went out to start making breakfast, and his friends were over. All I overheard were them making comments about how 'his voice sounded lighter' and 'he seemed more at ease' and how they were 'happy he was with me'. And then I woke up. I know, or at least it felt like, he was doing that to get my over my insecurities. He was tired of me feeling insecure around him so he made me just 'get over it'. But like the first dream, it felt like in some way this all actually happened. It felt so real it's unsettling. And like the first dream, the feeling is lingering on and even though this dream happened 2 nights ago, I still feel odd about it. But this time I feel really uneasy and almost stressed over it.

I've had 'real' dreams before but the part that has me so 'weirded out' over it is how vivid he was compared to other dream figures and how the feeling lingers for me, and how I feel so uneasy this time.
I just want to figure out what this is, why I'm having these dreams, and how/if I can get them to stop.

As far as a description of him, I would call him a few years older than me, maybe mid-late 20's. He seems exhausted but not tired, like mentally/emotionally worn out. He always has this look on his face like he's completely uninterested in everything around him except for when we're talking - he doesn't loose the uninterested look but shows a little more curiosity into what I have to say. He's somewhat soft spoken but he doesn't need to repeat himself to get his point across. Naturally red hair, cut short but not buzz cut, dark but clear blue/green eyes that really stand out. His brows are always furrowed. Short but clean, trim beard, always dressed in grays, and has a tribal-ish tattoo on his forearm. I don't know the exact pattern, I've never paid attention to it or anything, I just know it's there. He's about 6'0 or so, average weight for the height, not significantly muscular but looks like he probably has a physical job. He seems like the protective type, all along it feels like he's trying to help me or something but I still can't shake the uneasy feeling over it. And why he's so vivid. I just don't know what any of it means and it has me a little stressed out at this point.
