What are wanting and wishing dreams about?

As the title suggests, I just woke up after experiencing this and feel very weird.

In my dream I was in a mall type of thing at night and this stunning japanese woman bumped into me asking if I had the time. I said yes and continued walking around this mall. A little later I found a huge set of stairs and slid all the way to the bottom on the railings.

At the bottom of the stairs, the girl from earlier was there and timidly asked me if I wanted to grab some food with her. I said yes immediately.

I then remember spending some time talking to her about random stuff, but finding her more and more interesting and attractive. Her friends were cool and played in a weird funk-metal kind of band and asked if I wanted to be involved.

After talking she asked if I wouldn’t mind walking her up to apartment as it was super late. I of course obliged and went with her. After arriving she invited me in and I remember her place being absolutely huge and overlooking whatever city this dream was supposed to be in.

We talked some more about what her future plans were and how similar our goals were. It got to the point where we were close and kissing and eventually slept together. I just remember there being this weird warmth in my chest whilst this happening, and it felt like nothing I had experienced before.

After waking up from this, I feel almost hollow and honestly kind of depressed. I can still remember how she smelt and how I felt when she looked me in the eyes.

The fucked up part of this is that I’ve been dating someone for the past 6 months or so, and after this dream, dare I say that I feel less close to her?

Has anyone else experienced something like this? What does it mean? Is it my mind telling the girl I’m with isn’t the right one for me? I’m so confused.

So some people are going to read this and think I’m crazy, it’s fine though because I’m not sure if I am at this point. I was only asleep for a few hours but my dream lasted for years. I had a life and I fell in love. I’m trying to find him if he’s even real. Unfortunately the dream world was a bit different to this world and was dangerous and he died in it. He wasn’t just my sole mate he was my best friend and we fought together, taking on every challenge that the world threw at us. There was a group of us surviving, a few people I work with were there as well as some people I didn’t know prior to the dream, him and his brother. By the end of the dream I’d lost and mourned him, there were only a few of us left including his brother.

It wasn’t a nightmare, it was the best years of my life somehow and they never even happened. I remember them as memories rather than a dream, it feels like they really happened. I’m just hoping that maybe this is a second chance to find him and maybe I can save him this time. If he’s even real. I mourned his death once, if there’s any chance I can find him in this world I’ll take it. No matter how low the odds because that’s what you do when you’re in love and he’s my love.

I can randomly start lucid dreaming but I can't control when it happens. I know some of you have control of it and I was curious how you've all trained yourself to lucid dream when you want to. What's your method?

I'm 24 years old. When i was a young girl, my dad used to sexually abuse me and my sister. It was happening in the whole family, my uncles sexually abused their daughters and us, and my father did the same with other girls in the family. It was disgusting, really.
I used to have fights with my dad about that, I stood to him and confronted him a lot and he used to hit me for it until that ended when I was like 15 years old. He also used to physically abuse us and my mother all the time. Our lives when he was around were a fucking nightmare.
I had a little sister, we tried to protect her from all of that for a long time, I'm not sure we did though. When she was 16, she killed herself. She threw herself from the roof and died instantly. I know that my father was the one who caused that.
I'm telling all of that to say that I really hate him for a lot of reasons, not the ones that I can let go. We live without him now and whenever he comes, I don't talk with him and I try to not even see him. I go out, pretend that i'm sleeping or just ignore him. He tries to talk to us but we don't want anything to do with him. My sister and I are trying to fix what he did to us without any professional help because where I live there isn't that much of good therapists and we can't afford the good ones since we don't have jobs, so..
Today I had a dream that I was having consensual sex with him. I want it to happen and I felt good. I don't know what does that mean. When I'm awake, all I think of him is that he is a pathetic, worthless old piece of shit, and If you saw him or dealt with him you would agree. So I'm so confused about that dream.
Normally when I have a weird dream, I talk with my boyfriend about it and he tries to help me figure it out. By the way, my boyfriend and I don't have sex because I'm having troubles with my sexual life, and that's very okay by him because he's giving me the time I need before trying to have sex. So now I can't even talk to him about that fucked up shit to help me. Does anybody have any explanation for this or any Idea what is that all about?
Sorry for talking too much but I was trying to give you an idea about the whole situation.

Has anyone else experienced it yet? I basically woke up climaxing and it was really intense, unique orgasm. Wish it'd happen more often. Until then I had no idea it's actually possible to cum just by mental stimulation, especially since I can't do it without stimulating my clit when awake.
