my first paranormal experience - the doorhandle situation

so this happened around july of 2023 when i was 17 years old, and ive been thinking about this frequently with no explanation or encounter sense this occurred.

so it was around 12am, i just got upstairs from playing video games and a few minutes after i got into bed i hear a jiggling sound in the direction of my door. i turned on my phone flashlight and saw my doorhandle, witch is a lever type door like this, jiggling like it was moving up and down. i assumed it was my brother fucking with me and kept on watching a video.

a few minutes later, i hear it happen again. so i decide to get up and get a closer look, then i decided to open the door to try to catch my brother. but when i opened it while it was shaking, i felt no resistance and saw nobody behind the door. the other side even kept on shaking after i opened it for a second or two. i looked around the hallway and the bathroom seeing if it was my brother but i saw nothing.

a few minutes after it happened for a third time, so i got up real close this time with my flashlight and i could see it moving in like it was going to open. it wasn’t moving that much in but it was still noticeable. i opened the door again while it was shaking and yet i saw nothing even after looking around again. its never happened again

in the 2 years thats passed sense that happened its never happened sense. the only thing i know about what happened that it wasn’t a dream. it was real, i felt and heard it. i’m a agnostic and a skeptic, so i don’t really believe in this stuff but no matter how hard i try to find a natural explanation for what happened i cant. nobody else really believes what happened but i know it did. if anybody has any insight to what could have happened, please let me know.
