Sagittarius are often dreaming about things just out of reach. "Ruled by Jupiter, planet of luck, expansion, and optimism, Sagittarius' always crave 'more,' Thomas explains. "Because they desire so much stimulation, this may actually mean they're up late into the night checking out memes, chuckling watching videos, or gossiping about something new." They don't look at sleep as much of a priority as some of the other signs, but may pay the price in the morning when they're still sleepy and reach to grab their favourite choice of caffeine.
