tingling legs worse with nightmares ??

once or twice a week i wake during the night with a tingling feeling in my lower legs it doesnt last long maybe a miniute or so its like a sweeping sensation my legs also feel hot it usually passes quickly and i drop off back to sleep but last night i had a nightmare and woke with the worst feeling in my legs ever it was the same sort of feeling but much stronger my heart was beating like the clappers the tingling was really intense could it have happened because my heart was beating faster ? my bloods are ok between 4.8 and 5.6 pre food and ave 6.7 after meals should i see the doctor about this thanks
