Shhhhhhhhh....it's OK....You have just lived on an Alien outer space. industrial complex, space station for too long. You are suffering from Post Traumatic Stress disorder. These are called flowers. The pretty colorful winged creatures are called Butterflies. They sip nectar from the flowers and help pollinate the flowers so they can live on. This is called nature because it's all natural. Don't be afraid I'm glad you are back here on earth and can see the natural world. That said, try to avoid humans many of them are a little crazy, and some will just kill you for the money in your pockets. By the way the flowers smell good, and the butterflys are fun to watch....relax...you are home on Earth.
