Project Theta 27

You decide to stay by the tree. After a while, the girl is engulfed by light, but the light stays there, shining. The sun never sets and everything is the same, except for the occasional breeze that ruffles the tall grass. Time has no meaning to you. you dont know if its been years, weeks, days, or a few minutes. The shining light remains. Your curiosity comes up. What is this strange light?
