Are intrusive feelings a thing? Like ‘feeling’ like you are what you fear

Intrusive thoughts are unwanted and cause stress which mine do but also when I’m mad I get this rage feeling and say I wanna stab someone like that feels like a. Want not intrusive why am I saying “ I wanna “ :(

for me, it's like there's two folders of my thoughts, 'main thoughts' and 'sub thoughts' and it's like a background voice of my background voice, you know? like so quiet and irrelevant but it's still here and i can try to ignore it but not fully and it feels like it's just really nasty, like it's warring with me, never shuts up and just keeps nagging me with those thoughts

Please how can an intrusive thought be distinguished from our own thoughts ?
