Hi there. I have had a few episodes in the past that I can't identify. Any suggestions would be appreciated. In essence, it all started when I started taking SSRI's for OCD. Every 2 weeks or so, I started having these episodes that lasted about 10, sometimes 20 minutes , where everyone's voices seem louder than usual, like they're screaming at me. It's a very unpleasant experience, very similar to those nightmares one gets when having a high fever. Has anyone else experienced this? 

THank in advance
