Lingering Presence

A dark, lingering presence haunts a woman late at night alone in her bed.
Here is a preview of the story.
“Like many, I sleep with my door closed. One night, however, I noticed a tapping at my door, like someone was knocking quietly – nothing super loud, but it got my attention. I noticed it night after night, so I began to sleep with my door open. One night, a couple of weeks before Halloween (2019), I woke up to this dark/gray image hovering in front of my face. It completely took my breath away and freaked me out. The image floated upward toward the ceiling. It contained a bright green light in the center of this shadowy cloud with different colored light beams moving within it. Then, it suddenly disappeared. I was terrified.”
