Night panic attacks?

I get night panic atacks,i just wake up feeling my heart beat, i try falling back to sleep but i feel like im geting adrenalin shot the second before i almost fall asslep like my heart beats harder, i start panicin and when panic attack stops i start shaking like its freezing but in reality its actualy hot i dont shake that much when i get day panic attacks it kinda different,it doesnt happen every night anyone experiencing this?

Have you had your thyroid levels checked?  I have the same symptoms and was just finally diagnosed with a thyroid disease,  just started meds so I'm no better yet, I sympathize with you because those night heart racing moments and sleepless nights are hell.   Hope you feel better very soon, 

I didnt chech my thyroid levels i will in the future

Horrible! Just happened to me. I was sleeping then bam!!! My heart was racing so fast I didn't know what to do. I just walked around the house. It's still not all the way back down but here I go again
