I know about sleep paralysis and there is several information about it, available over literature.

Sleep paralysis is a temporary inability to move or speak that occurs when you're waking up or falling asleep.

But I never read about sensations of some electric current passing through an individual as shown in this figure from top to bottom during sleep. It doesn't comes under the category of sleep paralysis.

When I searched over internet [1], I found almost no proper material to read science behind it.

Is there any research done on (or at-least recognition in literature on existence of) such sensations while sleeping?

    $\begingroup$ The self-help component has been successfully eliminated by your edits, but I leave it closed as its still based on anecdotal evidence - The sensation of current flowing is not framed in terms of Psych or Neurosci. $\endgroup$ – AliceD Nov 5 '19 at 10:27
  • $\begingroup$ @AliceD I am hoping that the dream tag supports the question. Do u mean that it was never dealt in literature? $\endgroup$ – hanugm Nov 5 '19 at 10:33

    $\begingroup$ @hanugm I'm still not clear on what this question is about. The concept of "sensations while sleeping" is confusing to me, as people don't generally have sensations while sleeping (that's kind of the point). If you are referring to dreaming of being electrocuted, then the question should say that (though note that it won't help this question as we don't do dream interpretation here). If you are referring to something else, then please clarify. $\endgroup$ – Arnon Weinberg Nov 5 '19 at 15:30
