A childhood belief about under my bed

when i was a little kid, i believed that there were monsters under my bed because one time when i was like 5 my mom got mad at me for ruining her new bedrom wallpaper (i colored over it lol) she was like 'Leah! Come here!' i came and then she said 'did you draw pictures with a sharpie, all over my new walls!?' i nodded slowly and then she was like 'Leah, i can't believe it! you should know better! that was a very naughty thing you did! the monsters under your bed are gonna get you!' obviously she was just kidding she was mad and that's why she said it. so that's what i thought until i was 7 and a half and i was thinking about the time when i was 5 and she told me that there were monsters under my bed and that i got terribly scared from then on that one day, the monsters from under my bed would jump out and eat me. so i walked up to my mom and said, just wondering, 'mom, is there some kind of spray you can buy at the store to kill the monsters, like you do with the ants that get in the house every august?' she took a deep breath and she was like 'dear...there are no monsters under your bed, and monsters are make-believe. i'm sorry i ever said that, i was just mad.' i was in so much shock lol!
