Rooms of nothing with nothing to do is my second worst nightmare after becoming permanently paralyzed.

I have Hypokalemic Periodic Paralysis (HypoKPP) in addition to SPD. HypoKPP is sensitive to adrenaline rushes. SPD triggers adrenaline rushes for those who are Hypersensitive to sensory input. The HypoKPP causes the major of the motor issue and all the paralysis/non-responsive problems. I inherited it from my mother. It is a fairly rare condition so I wouldn't expect most SPD people to react to sensory overload by shutting down like I do.

Since SPD is triggering adrenaline rushes, I would expect a "normal" SPD individual to experience Fight or Flight modes. Fight mode would cause anger problems and potentially fighting until the sensory stimulous is ended. Flight mode would cause the person to flee until the trigger no longer has impact on them.

In my case, the adrenaline rush causes the Ion imballance that triggers the HypoKPP, which is why I temporarily become paralyzed and non-responsive until the adrenline rush resolves.
