Paranoid thoughts

Hey , I’m 19F I have been struggling with my mental health for as long as I can remember. I’ve been back and forth with therapists since 11 and just before I turned 19 I was finally diagnosed with ocd. While I definitely know I have ocd there are some things I have been questioning as to whether are part of ocd or something else. I suffer with very vivid paranoia and have since I was a child. For example I see shadows out the corner of my eyes. As a kid I was terrified of paranormal things at night I would sleep under my covers and refuse to move and be petrified that if I moved or came out something would be there staring at me ready to harm me. Now it’s silly things such as if I’m in the kitchen at night I will get really anxious and feel someone watching me or cold air on my neck of something behind me then I’ll have a voice or thought I’m not sure in my head mocking me telling me they are behind me and then laugh at me I also get a really disturbing image of a random scary person and think I hear things like tapping but I believe that’s just my brain tricking me . I sometimes feel frozen with fear. I’ve had literal screaming matches in my head. Does anyone have similar experiences and could it be ocd ?
