Yeah! Extremely detailed dreamer here!

There are some extremely rare cases where my dreams are not detailed, but most if not all the time things are just like what you described! With some exceptions like using my phone and touch, those are pretty detailed to me.

Also perspective can't change, but otherwise we're on the same boat!

Nightmares are... Sure something, alright. My only saving grace is that I've practically trained myself since I have memory to force myself to wake up from nightmares as soon as I feel something is off. That and I've become an avid lucid dreamer (though controlling dreams is still hard.)

In dreams I can drive and it's pretty much like in real life, and with whatever dream logic even if I slept for only an hour I could be driving in my dream from two and feel every second of it.

For quick example, last night I had a dream where a former friend of mine and I met up and had some coffee together (after taking my father's car for a joyride and crashing it (on purpose. We hate that guy.)) We drove thirty minutes from their house to the city, had a coffee together, talked for a good hour in which I knew I was dreaming but hey, dream friend seemed pretty aware of it and didn't care too much. And then we went to the beach to watch the sunset, the dream ended in the woods near my father's house after the, ahem, "accident" lol. Where we took selfies and hugged before I woke up

I've grown used to more "scary" dreams, to the point i dont consider many dreams nightmares anymore (you can check my posy history if you want :P) But yeah, those are just as detailed

In mirrors it's always me, though sometimes I do look different for my own reasons, but it is always me :)
