Not sure if this has been discussed before, and this is probably explained further in the series.
For what I understand, the ritual on Mhybe has made her the container of a whole new world/warrren/dimension where rhivi, Imass and the Wolf Gods will live, and she will be inmortal. Imo this is excactly what Burn is, and the all the events we are reading are taking place in the world within Burn. This makes me think that therefore, Burn is, like Mhybe, sleeping in another higher dimension world... Not sure I express myself correctly.
