I feel Plague of Dreams is a very strong iteration of the Companion Chronicles. Featuring an intriguing mystery figure called The Player conducting a strange combination of a performance coupled with an interrogation of sorts, while also kind of being a rescue mission and a lead-in to the Tenth Planet. It's a strange story, but a creative one, and an audio that consistently kept my attention.

I've never been a big Polly fan but this is really her character at her best. Anneke Wills really does a good job as her and the Doctor, while I think Elliot Chapman is fantastic as The Player. All told, it's a very cool audio, reflective of the Doctor, his character, and his future. Some fans might not like how it brings in hints of Time Wars to come, but I really like it as a sort of reflection on the franchise as a whole, and the tremendous ocean of content on the First Doctor's horizon. A really interesting piece that works well as a companion chronicle specifically - very optional but a thoughtful new way of looking at the character.
