I wonder if anyone else has experienced this and can shed some light on what it is and what causes it. As you can see from the photo every now and again I get what looks like grey mould appearing on my pillow, I think from either my saliva or cough or air breathed out at night.
I have bronchiectasis and I have asked the doctor and consultant but they don’t know. It is definitely related to my breathing as it never appears on anyone else’s pillows in the family. It is intermittent and comes and goes. I’m sure it is some kind of bacteria, mould etc and doesn’t seem like a good thing. Has anyone else ever experienced this or got any suggestions? Thanks.
