AITA For Dealing With My Poo In An Unconventional Way?

So I (22f) was relaying this story to a really close friend of mine and she gave me a really gross look and told me I should've known better. Before I tell this story. I have to preface that I was 7, and very terrified of the dark. Like Phobia level.

So when I was 7, I had this best friend. We will call her Lucy. I was very close with her and had many sleepovers over a year and a half before this incident. This particular night, I was having a very vivid dream about the childhood show Hi-Five (Australians will know) So i was on stage with a particular stage member (that I cannot remember now so I'm sorry), and I took a shit in my dream. I remember then waking up and laying for a moment. Realizing that I infact took an actual shit.

Noticing that it was pitch black in the entire house, going to the bathroom for me wasn't exactly the easiest option to someone who is horrified of the unknown. So, I evaluated my options. I could run screaming to the bathroom and wake up the entire house. OR, I was going to sleep in my poo. Even 7 year old me thought that was gross.

It hit me.

I grabbed the log. White-knuckling it with all my little might, and pegged it underneath the bed (I feel its important to know that while me and my friend shared the same room, we both had separate beds, on the other side of the room from each other.) Not only did it hit the wall with full force, but it had enough force to create a noise on the carpet as well. So once that was removed from my comfy Hi-five pants, I went back to sleep.

By the time I woke up in the morning, The Australian heat had settled in and found it's way towards my fecal incident. Not only had it caused the entire family of 3 to start gagging, frantically trying to find the smell, but it had also melted into the carpet a little bit. So that was a very fun discovery when I was a child. I already knew I was fucked.

When Lucy's Mother, We will call her Michelle - came to investigate Lucy's room, she found my accident about 2 minutes into snooping through her room, our bags etc. - mom routine.

She looked me straight in the eye and went "Did you shit underneath the bed?" In almost an impressed tone mixed with anger. The space would have been awkward as hell to fit my ass underneath, especially considering it was closer to the wall so i would've had to crawl to the back.

I thought it would've been better to say back "No, I threw it underneath because I pooed my pants in bed." She then went off at me, saying how I should've used to the toilet, I'm barbaric, whilst sending me outside to play on my bike with Lucy until my mother picked me up about 10 minutes later as she was in the area.

So, reddit. AITA for being too afraid of the dark to go shit at 7 years old? I mean I understand the mothers crash out now that I am an adult who understand rentals etc. - but even my friend 15 years later thinks I'm disgusting & a bit of an ass for throwing it. I wasn't thinking!! I was half asleep.
