Is it normal i have thoughts of killing my parents and etc.?

i grew up pretty normal. i did not experience being bullied. i cannot say i'm popular but i have lot of friends and my group of friends are popular. i have loving parents and relatives, i'm actually pretty close with my parents. my mom and I share the same interest/hobbies reading and watching dramas and we like to talk about it and share updates, my dad and I like to watch anime and joke a lot of times.they are actually not that strict to me when it comes to going out with friends or sleepovers to far places or when i can't come home because of school requirements as long i just text or call them. but on the other hand they are strict to what i wear no sleeveless no shorts just skirts so when they are not there because of work (my mom comes home late, and my dad is not always at home), i usually wear those kind of clothes without their knowledge. i can't even cut my hair actually it is because of our religion. sometimes i actually taught of killing them (not just once but many times) and how easy my life they are gone i know it's kind of weird because i depend on them. i think of different scenes of their murder and how to make it look like an accident, and i dismiss them because it would be too troublesome if i got caught. i like watching gory or brutal films or read novels that are about murders actually my course is psychology and i'm planning to pursue a career of being a forensic psychologist because of fascination with death and murders. i love my parents, and i don't like hurting others or others hurting me i just want to be the bystander or witness.i also have troubles forming attachments to my friends i can go on forever without contacting them, i found it troublesome. and i have also another secret i like watching or reading porn and not just the regular one i like topics about incest and bestiality but i found them gross in real life in my situation.
