Any advice? And is this a sign of OCD or am I just trippin'?

I would encourage you to speak with a mental health professional. Suicidal ideation and thoughts of harming others are serious and should be addressed in a serious way by a professional.

Lots of people have random thoughts, but persistent intrusive thoughts, especially causing harm to others, is a red flag.
Could be a simple chemical imbalance, resurfacing trauma, or a mental illness. Better to seek help than hurt yourself or anyone else. :) Glad you were brave enough to post.
The US has a 988 phone number to call anyrime that you need to talk to someone.

Thank you so much for trusting us with your difficulty. It took courage to tell us.

Those kind of random thoughts are completely normal. It’s ok to look at them and tell them “thanks, but we’re not going to think about that right now.” Then you can change your thoughts by looking at happy pictures of puppies or flowers. You can also listen to uplifting music.

Where OCD starts is when the worry about the thoughts interferes drastically with your life. If it keeps you from activities of normal living, that’s a concern. You haven’t described that, so I think you’re OK.

Every once in a while I’ll have one pop in my head. I’ve learned to identify that it’s not my regular type of thought, tell myself, “Well that was strange,” and move on.

Talk to a professional. Period.
