I really dont know how to put this but recently, close and well-known concepts have become distant and I’ve forgotten about their meaning. eg the concepts of stuff like mankind, economy, education, hierarchies or even relationships all seem very odd and foreign. I also lose a lot of my memories and cant recall most stuff that happened more than a few months ago. I’ve also had psychotic episodes (luckily very few) and a lot of derealization and delusions, could they be related with this? any help is greatly appreciated
