So how high do you have to be to walk above the clouds? 85th floor, that’s the answer. German photographer Sebastian Opitz has been getting up at 4 a.m. and taking trips to 1.358-foot-tall (414 m) Princess Tower in Dubai to capture these dream-like pictures of skyscrapers piercing the fluffy clouds and the fog. Among them you can also see Burj Khalifa, the world’s tallest building.

According to Opitz, thick fog is rare in Dubai, it occurs only four to six days a year and evaporates after 9 a.m. Seems like tons of dedication and liters of coffee had to be used to capture these spectacular moments. But the thrill must’ve been completely worth it – it’s like a whole different world up there!
