Recently, I've discovered mold in the plastic bag I was storing my toothbrush in. I put my toothbrush in this bag to shield it from toilet spray since my sink is awfully close to the toilet

In hindsight, this was a stupid idea. There was no actual mold on the toothbrush itself which is why I took a long time to notice. I've also been having insomnia for a month now when i've never had it before, and I have had this insomnia before discovering the mold. Can (probable) mold consumption cause insomnia? Could this possibly be linked or am I just paranoid? Can this amount of mold cause deleterious effects?

My toothbrush head was presumably touching this mold for ~3 months. pic related

this is the only helpful board on this site, thank you.
