My Lucid Dreams

I've had a dryspell of over two weeks, but now I'm back !
This dream was pretty short because my cat woke me up

Lucidity: 8/10
Vivacity: 8/10
Control: 8/10

I'm in a modern luxury hotel room, on my laptop. I've got an awesome view on a rich, almost futuristic city with high buildings and an ocean on the left. Apart from the floor and the furniture, the hotel structure sort of reminds me of a friend's apartment.
I'm watching a friend of mine's video on youtube; it's a weird magic video. Accidentally, I copy the video on an editing program and freak out for no reason at all.
I become lucid.
There's no need for any reality check: I know for sure that I'm dreaming.
I brows the program's options and find a cool-looking key: "wooden". I click on that and enter the screen... I land somewhere in the city in which my hotel was at. I see branches coming out out the ground and buildings, green stems and leaves progressively growing on them. Eventually, full trunks grow too, until the place resembles a city that would have been deserted for hundreds of years.
People in front of me back up slowly, looking at me with awed stares, as if I was the Devil just coming down to kill them all.
Well, they're not exactly wrong...
Up on the rooftops at my right, a friend of mine stares at me. I feel like he is the hero whose duty is to stop me.
Nah f*ck that.
I walk a bit in the streets, with a masked guy who followed me. Eventually we arrive to a sort of "bridge"; the beach is close to my left, in front of me is a ~5 meter drop onto a calm road.
The masked guy asks me how big I want to become, and I scream "I want to be expandable !" (wut?).
I've already grown about half my size, but I want more.
I walk up to the fence that is supposed to prevent me from falling onto the road, cross it, and adopt a suicidal pose: my feet half way in the air, holding myself onto the rail behind me.
I focus on the buildings in front of me, with the masked guy watching me. I slowly take a few steps in the air, but I'm not falling: my body extended to the ground. I walk around a little bit, I can hear my feet pounding on the floor. The masked guy followed me. He grew too, but not as much as me.
I hear weird, loud noises coming from everywhere, until I wake up and realize my cat was scratching on my door
