Very speculative, but if this could some day be adapted to humans, I&#x27;m deeply curious how (if at all) this will figure into treatments for PTSD.<p>Considering that debilitating nightmares are a common and harmful symptom (as it&#x27;s hard to function when you spent the night back in $trauma), I wonder whether temporarily &quot;switching off&quot; dreams during treatment would be helpful, if nothing else, allowing the person the occasional restful night.<p>But, on the other hand, it could be harmful, too, if the traumatic dreams are actually a healthy (if not pleasant) manner of processing the trauma.<p>Interesting!
