Science headlines urgh.
The development here is that they've figured out a model of the actual interaction thats happening during the transition phase between nREM and REM, which is pretty cool. We've known dreams are an artefact of memory processing for a long time, as well as that REM is basically long-term memory thunderdome. But the actual mechanisms underlaying this, in non-abstracted terms, are still hugely complex and largely not understood. This is a big step forward (if verified) towards the goal of unraveling the full memory encoding process.
