Random heart rate spikes whilst doing nothing, happens whilst laying down or driving. body sometimes go into a hypertensive state, if i can call it that. blurry vision, light headed, nauseous, dizzy. all this happens when the heart rate goes up.

See your doctor?: Since your post contains no question, I will guess that you want to know what to do about it. The numbers say that in a 23-year-old, it’s probably nothing. In your case, however, it is prudent to visit a doctor to rule out some kind of cardiac arrhythmia or congenital heart defect, which do occur in young people. I suggest sooner rather than later.
