Hi guys, I always thought that external stimuli while dreaming was heavily distorted or otherwise no noticable but this morning it nearly caused me a nightmare.

It must've been around 07:00 in the morning when I was dreaming, the dream itself wasn't so interesting. I saw someone get shot and killed after which I got home and just waited for something with my family in the same room. Then I heard the alarm of the dryer upstairs which indicates the filters are full. So I go up and clean out the filters cause the alarm is loud and annoying, I go down again and sit down but notice the alarm is still there. It is a lot louder than usuall and it seems to follow me where I go, I ask everyone about this but they claim not to hear it. I begin panicking thinking it's tinnitus or something from the loud music I sometimes listen to. After 5 minutes I nearly go crazy but then suddenly I wake up dazed and still hearing the alarm, the room with the dryer is across my bedroom so even though it hurts getting out of bed instantly I had to. That's when I realized how clear and loud the alarm was in my dream without waking me up instantly, right now I'm thinking if the same thing could be done with lucid-inducing sounds. Like a message telling you you're dreaming or something, it can be quiet loud cause IRL I can hear the alarm of my dryer downstairs through multiple doors.
