Trippy story some kid told me at a party

i didnt know the kid but he said him and some friends were having a party in the woods during high school. they all had some shrooms and decided to go explore, while walking through the woods they came across what they thought was a gnome. he said they chased it around and finally one of them tackled it and grabbed ahold of it. one kid ran back to get the garbage bag for emties so they could put the gnome in it. so they had the gnome in a bag and went back to the house to crash for the night. the next morning they woke up and someone remembered the gnome and that they put it in the closet. they werent sure if it really happened so they opened up the closet to see what the fuck it really was and found a little black girl sitting there staring at them. he siad they bugged out and ended up giving her 50 bucks and told her to walk home and never come back here.
