Is this possible or this is just my ocd

So i live with my mom and i have a dog.We also have alarms in our house.Last night as i slept(i sleep with my mother) i had a dream about a boy(who i know)touching me on my vagina and i was getting wet.I was feeling the touch very realistic.When i woke up i had a loot of white discharge( it is my ovulation day).At 5 am in the morning my dog started barking for like a minute and then stopped.I have OCD and anxiety and i often create scenarios in my head.Could somebody went into my house and raped me while i was sleeping?Even though we have alarm system,i sleep right next to my mum+ our dog sleeps on our bed.I am not a virgin but i don’t feel any discomfort.Should be worried or this is just my mind creating fake scenarios?I know it may sound strange but i have these thoughts often so in my mind it looks fine.+I masturbated last night right before i went to bed,could this dream be because of that or i was really raped?
