Waking up in the middle of the night

For past few days i have been up in the middle of night , quite disturbed , but unable to exactly locate the cause behind it.Iam just, at that moment reminded in a nightmarish way ,about some urgent need.I can sense my heart pound, and my breathing to be faster, i feel like the fleeing off to some safe refuge, but there is at the back of my mind , an urgency to pray about something or someone.I pray, i try to calm down, for it is not a pleasant experience, i remind myself that God is in control and He will not allow me to experience anything , beyond what i can bear.
