An Unusual Flower-pattern

Last night, I was getting ready to sleep and nothing felt strange. When my mom closed the lights and said good night to me, I began to sleep. After awhile, I couldn't sleep and twisted and turned, so I decided to lay still and just stare at the ceiling. A green outlined flower patterned symbol began shaping in front of my eyes and I got scared quickly. This has happened once or twice for a few seconds before so I hadn't thought much of it. But this time, it lasted for a long time. I was confused and soon, my whole room/my walls were covered in the green outlined flower symbol. It was similar to those glow-in-the-dark sticker things that you plastered onto your wall as a nightlight or for decoration. For example, in the movie Tangled, Rapunzel sees the golden figure of the kingdom's represented symbol on her walls and it kind of stood out to her/glowed almost. For me, it glowed green. Then, another symbol appeared (red) and I also didn't know what it was (I forgot). Usually, there's light outside of my bedroom because of the kitchen/bathroom but instead of light, it was filled with sprinkles of red, and so were other parts of the room. It's hard to describe but the glowing green was spreading more and more throughout my room and I was getting more scared by the second. I tried putting on my shield (I'm Wiccan/Pagan) and all those techniques I've learned but nothing really happened. It didn't harm be either way and I couldn't sense if it was good or bad since I was in fear. I closed my eyes to see if it would still appear (like if I mistook it for the shadow of my retina or something), but when I did, it was darkness. No faded outline or orbs or any sort. So I knew that I wasn't seeing things.

Could anyone help me on this? Does anybody know what this could possibly mean? Is it bad? Is it evil? Is it a stamp of protection? Please comment on this asap as I would like to know.
