@Kered All the Death Rattle samples were taken in the secret part of the hospital in Kharbranth, in which case this wouldn't be an "authentic" part of the death rattle. This would be the subject waking up and noticing that there is a nurse (Silent Gatherer) by his bed draining his blood, then perhaps seeing into Shadesmar in the moment of transition (and seeing a Cryptic).
Therefore, the significant part of this would only be the last part about Shadesmar, since the first part most likely just refers to the mode of the subject's death.
