Sleep paralysis or awake?

To set the stage, my grandmother has a vacation house on an old burial ground where my father experienced many paranormal events as a child. When I was 14, my family stayed there for a few nights.

The vibe felt eerie, but I didn't think much of it at first. The room where my siblings and I slept had 4 bunk beds, 2 on each wall with a narrow walkway between them, along with a window, empty closet, and a mysterious locked door. My older sister had previously gone inside the off-limits room with our cousin and heard strange noises, sparking their curiosity.

Overall, the downstairs gave me an uneasy feeling, so I wasn't looking forward to sleeping there. That night, around 3-4 AM, I suddenly awoke and saw a tall, dark figure with glowing white eyes staring at my sister. Sensing I was awake, it whipped its head toward me.

This was no illusion - I knew it was real. Paralyzed by fear, I felt unable to move or speak, staring back at this shadowy entity. Summoning my courage, I flipped over to face the wall, squeezed my eyes shut, and tried to fall back asleep.

I told my mom about it in the morning but she stopped me from mentioning it to my grandma. The experience really freaked me out.

What do you make of this?
