Started developing what i describe as an involuntary deep or sharp breath. either sitting or before or during sleep to where it would awake me. sometimes i get like this hard thump or jerk that causes me to jump while im alert or sleep, heart races?

You need a good evaluation by your MD and possibly sleep study.

Gasping maybe a sign of a Sleep Breathing Disorder (OSA) which is related to cardiovascular events, high blood pressure, diabetes, cognitive decline & urinary issues. A home or lab sleep test along with a STOP-BANG or Epworth Sleepiness Scale is needed for a diagnosis by a Sleep MD. Treatment is CPAP, Oral Appliance Therapy by a dentist, or surgery. See your primary care physician soon.
