I had a really disturbing dream

TW

I had a dream that me and my siblings were out and i got of the car to go to a store but my sister stayed in the car. As i was going back in the car I saw my dad having sex with a girl in the car and my sister saw too. When I came closer I told my sister to get out and she threw up all over me and as I was trying to grab something from the car he like finished over it and it was cover with semen.

its such a graphic awful disturbing dream. I feel so bad for dreaming this. I feel traumatized by my own brain.
