I've been working for my boss for a few years. 

Shortly after I started working for my employer, they revealed to me that they are bipolar and have been taking meds for some time. This revelation made no difference to me, and the workplace seemed to be prettymuch fine- until the past month or so. 

Lately, my Boss has been saying things to me that sounds like they are living in a slightly different dimension than the rest of us. I don't know if it's gaslighting, dissassociation, or what, but it's very worrying. Is this possibly a sign that my Boss may not currently be taking meds? I've not seen this behaviour before.
