I swear on my mother’s grave that everything I’m about to tell you happened exactly as I describe it. No embellishments, no tricks of the mind. It was a Tuesday, the last day of October, and the air outside my apartment carried that metallic bite of winter’s approach. I was alone in the living room, my roommate having gone to visit her folks for the holiday. I remember the clock on the mantel: it read 9:47 PM. The radiator hissed like a dying snake, and the wind rattled the old windows in their frames. I was restless, as I often am at night, so I took to pacing the length of the room, my footsteps echoing on the hardwood floor. Five steps to the window, five steps back. It was a ritual, a way to settle my nerves. After a few circuits, I plopped down on the edge of the sofa, the springs groaning under my weight. A faint reflection caught my eye in the windowpane—not my own, but something else, lingering just beyond the glass. I leaned closer, squinting into the darkness of the courtyard below. That’s when I saw it.
It wasn’t a hand, not really. It was a shape, roughly the size of a human hand, but composed of a soft, pearlescent light that pulsed gently, like the glow of a firefly trapped in amber. It hovered a few feet beyond the window, at the level of the second floor. The light was so bright it cast faint shadows on the soot-stained bricks. My breath caught in my throat. I thought, absurdly, of an angel—the kind you see in old paintings, with fingers of light and a halo of pure white. But no angel would be hovering outside my dingy window on a Tuesday night. I pinched my arm. I didn’t wake up. The light didn’t flicker or fade; it just held there, patient, as if waiting for me to make the first move. I found myself moving closer, my nose nearly touching the cold glass. The light intensified, and for a heartbeat, I saw something inside it—a pattern, like the veins of a leaf, or the lines on a palm. Then, as quickly as it appeared, it darted sideways, vanishing beyond the edge of the window frame. I gasped, stumbled back, and knocked over a stack of books. The clatter was deafening. I stood there, trembling, my heart hammering against my ribs. I wasn’t scared, mind you—it was too beautiful for fear—but I was shaken. I had to tell someone.
I ran to the hallway, where my sister was on the phone with our mother, her voice a low murmur. I must have looked crazed, because she put her hand over the receiver and raised an eyebrow. I mouthed, ‘Come here, now.’ She frowned, told Mom she’d call back, and followed me into the living room. I pointed at the window, my finger shaking. ‘There,’ I whispered. ‘There’s something out there. A light. A hand of light.’ My sister rolled her eyes. ‘You and your night visions,’ she said, but she walked to the window anyway. She peered out, her face blank. ‘I don’t see anything,’ she said. ‘It’s just the streetlight reflecting off a pigeon’s wing or something.’ I shook my head. ‘No, it was there. Bright, like a lantern. It moved.’ She sighed, turned, and put a hand on my shoulder. ‘Maybe you’re tired. Get some sleep.’
But I couldn’t sleep. I lay in my bed, staring at the ceiling, replaying the vision in my head. The light seemed to have imprinted on my retinas, a ghostly afterimage. I must have dozed off, because the next thing I knew, the room was bathed in a cold, blue glow. I sat up, my heart pounding. The glow was coming from the window. I crept out of bed, my bare feet cold on the floor, and peered through the curtains. The thing was back, but this time it was different. It was larger, more defined, and it was pressed against the glass, as if trying to get in. Its edges were no longer smooth; they flickered like a candle flame in a draft. I could see it more clearly now: it was indeed shaped like a hand, but with long, tapering fingers that ended in points. And it was leaving something on the glass. A residue. A thin, silvery trail that spiraled and looped, like a signature. I watched, mesmerized, as the hand moved, drawing a symbol that looked vaguely like a eye with a horizontal line through it. Then it withdrew, and the glow dimmed. I stood there, frozen, for what felt like an hour. When I finally moved, I touched the glass where the residue was. It was cold, colder than the glass, and it left a greasy film on my fingertip. I wiped it on the wall, but a faint shimmer remained.
The next morning, I told my sister everything. She listened, her arms crossed, a skeptical twist to her lips. But when she saw the glass, her composure cracked. The silvery pattern was still there, etched into the pane as if by acid. She ran her finger over it, then looked at the residue on her own skin. ‘We need to move,’ she said, her voice barely a whisper. I agreed, but neither of us knew where to go. That afternoon, while we were packing, I noticed the pattern on the glass had changed. The eye had grown an iris, a dark pupil that seemed to look directly at me. And below it, new symbols had appeared: a crescent moon, a series of concentric circles, and a word that I couldn’t read, but which made my stomach churn. I looked at the window and felt a sudden dread. The hand had come back, and it was not just a hand anymore. It was a whole arm, reaching through the glass—no, from the glass—its fingers wiry and jointed like a spider’s legs. It made a soft, sucking sound as it pulled itself free, and I ran. I screamed for my sister, but she was in the bathroom, and I heard the door slam behind me. I raced down the stairs and out onto the street, not looking back.
I have not seen my sister since. The police found our apartment empty, eerily tidy, the window intact and clean—not a trace of the pattern. But I know what I saw, and I still feel the cold residue on my fingertip if I press too hard. A week later, I received a postcard in the mail. It was a picture of a lighthouse, but the address was my own, and the message was written in a handwriting I did not recognize: ‘I’m still here. The lantern in the glass is a door. Don’t leave the light on.’ I destroyed it immediately. But at night, I often wake to find the windows in my new apartment covered in a faint, silvery sheen, and I swear I can see a shape waiting beyond them. I do not know what that thing was—angel, ghost, or something else—but I know it wasn’t finished with me. And someday, when I least expect it, the glass will glow.
