I just woke up from the most disturbing dream i have had in my entire life. If anyone here can stomach it, i need to understand it.
It started like a normal dream, i think i was playing some fighting videogame.
Then my little sister (she's 11) comes up and shows me something she didn't understand, she does that all the time because i explain things in terms children understand, what she showed me on mom's phone was pornography. I tried to play dumb and change topic to something else, but she kept insisting and i had to explain, i tried to in as vague terms as possible, she kept pressing me for more and more specific answers
She then out of nowhere brings up the topic of abortion, something she has never asked about before, once again i explain very vaguely as to not hurt her feelings.
Then she ends up saying that all of these things gave her an idea: she wants to have sex with me, so she can get pregnant and then have an abortion to feel what having an abortion is like. In my dream, i was so taken aback by that that it physically woke me up.
I tried not thinking about it, but i went back to sleep and i had a continuation of the same dream. In this continuation i was basically trying to avoid my sister or being alone with her at all cost, and i was trying to convince my parents to do some discipline without telling them exactly what had happened to protect her, i don't think i succeeded, and she kept insisting on me every time she got close. Then i started playing age of empires, and woke up.
A few other things happened in each dream but they don't matter as they are the typical disconnected dream episodes, mostly around some fighting game i have never seen before.
The thing is, i love my sister, and my entire family. I am no nonce and all of what she said repulsed me to no end, so, what the fuck was that?
My first theory is that i drank an energy drink for the first time in months and it's contents fucked me up, which may be truth but it doesn't explain what happened there.
My second theory is that my parents give their phone to my sister, which repulses me. I haven't seen her looking for anything out of place, she uses it for church music actually, but i know what is out there so the idea of her having access to that disgusts me.
My third theory is that it may have been some sort of extreme stress test, that i dream what could possibly be the worst thing that could ever happen to me. I got split between trying to protect the innocence of my sister, trying to avoid her, and trying to convince anyone else (my parents mostly) to give a fuck about what was happening, unsuccessful in all of those.
If anyone has any idea what the fuck was that, tell me.
