What’s the best thing to do?
my favourite thing would have to be driving around while LD. it’s a lot of fun.
but you have to think about the things you want to do in a dream 
if you can think it, you can dream it 
The best thing I’ve done was to actually accomplish a dream goal. The first one I succeeded at involved drinking a cup of lava. It’s a great feeling to accomplish a goal.
My favorite thing to do is talk to dream characters
Oh and looking in mirrors is sooooooo fun, every time it’s a different surprise
I haven’t had many yet, but two of the best things i have done is telling my Subconscious to take me somewhere interesting and flying really fast.
Eating random things.
I have to say flying! And traveling through the cosmos and also playing with planets like they were balls…
For me slowing time and walking on water.
Also seeing a sky full of hundreds of golden galaxies that swirled around.
probably flying aross beutiful landscapes with friends. 
Haha how did drinking it feel? Did it burn?
Anyways, the best thing I’ve ever did was fly. It is a wonderful feeling. Of course, I’ve never really done anything else in LDs (Most of the time they were way too short), so I can’t say what the absolute best thing would be, though I suspect it might be hurling fireballs at dream characters. 
Flying definitely! It’s such an amazing feeling to be free and just zoom around in the sky~!
The best thing wich I made in a lucid dream was to go to the dojo of the crossing of the lucide road
So far, Flying. Haven’t had many lucid dreams but… so far
Breaking stuff, and transforming into a wolf.
picking stuff up with my mind flying and creating DCs
