In my case the two tend to cluster together. I've found that the EHS is usually triggered by a small physical sound in the environment, like the house ticking as it cools. It was scary as hell for me when it first started happening, but I've grown accustomed to it. I've never gotten used to the sleep paralysis, but thankfully it is much less common for me. Both seem to be triggered by stress in my case.
