An Orb Passed By Me Last Night

Night while walking into my bedroom my room was already set on a dim light as I enter in a ball of light pass me then staged itself on the wall in front of me and vanished I had those chills again as if someone wanted to be noticed right after through the corners of my eyes left side I saw these dancing bright flashing lights with pink, blue, purple sparkly flashing about for about 3 to 5 minutes I didn't say a word it was about 1am. Morning hours then the dark shadow was 3ft from my bedside where I was laying down, I felt it was a woman she vanished after I looked at her briefly. I fell asleep but woke up like every hour. Now you can see you're not alone! The feeling I get is that it's a good spirit even though she was a dark spirit. Can dark shadow spirits be a good spirit? Would like to know for sure it would ease our minds. I also saw in the air at the bottom of my footboard, colors of purple and blue from the corners of my eye on the left side of my room. I also wonder if it was a playful spirit, just saying because it ran up before me wanted to be acknowledged before in vanished. Has anyone else felt the same way once before, having a spirit speed up before you just play or taunt with you? I would love to hear the explanations from you! I have a question on bed shaking mattress only as if someone was entering the bed this happens often too. Not sure if it's a good spirit I was never harmed by it but feels creepy just when I am ready to fall asleep it usually happens about 2x a week.
