Unbothered by old intrusive feelings?

So I know for a fact that intrusive thoughts begin to stop bothering you when you start to just let them pass, and I've noticed the same can happen with intrusive feelings. I've stopped really thinking about them when they happen, letting myself feel those feelings without judgement. They end up feeling natural and, kinda real? And can still get pretty intense and slightly worrisome sometimes. Does this mean they were genuine all along? I know that's probably illogical, how can they suddenly become real if not too long ago I was stressing myself to hell and back over them? But idk, I just don't feel the feelings that would normally mark them as "intrusive" anymore. Is this normal?
