I’m kinda freaking out right now. What mod could have added this?

Firstly I don't know if this is the right subreddit for this. I figured since it involved mods i could post this here.

I have been playing on this save for like 5 years. It started off as a world to play with my friends but as time passed on i was playing on it exclusively. Occasionally my friends hopped on from time to time even to this day.

Few years ago i started to play it with mods since vanilla got a bit stale. I downloaded many mods and deleted many. But have i never downloaded a single mod that could have done this. The most "horror" mod i installed was cave dweller and i doubt it can do something like this.

I was playing as usual in the what could be called "core" part of the world. This region is fairly close to spawn and not a newly generated chunk. It was generated in the first year of the world i believe (when it was still vanilla).

I did some building near the screenshot was taken and i started wandering in the area. Then in the distance i saw this weird tree. I went to investigate and saw this sign saying "make a wish". I got chills at this point. Then i turned around and saw a redstone trail. I took screenshots fast and quit the game.

Now i have to remind you that me and my friends are NOT from a native english speaking country and they are not the type of person to do this. Also it's been months since i played with a friend on this save and we were nowhere close to this region and even if they did do it i think they would try to make me find it.

What mod could have added this? I uploaded the screenshot of my current mods that i have if it helps.

edit: we play it by opening the world to LAN. Other than that i play on it by myself as you would play a singleplayer world. If my friend was trolling me he would have to do it while i'm also playing.
