Already on edge, it didn't take much. At first touch, the man's eyes flew open and he gasped with a cold sweat. For a moment, his surroundings didn't register. His mind was still flooded with memories and nightmarish imaginings. He didn't try to find out where he was, he looked around for a threat, or whatever had touched him. 

For a moment, he stayed still and tense, hands grasping onto the arms of the chair, read to move. 

However, after a few breaths, it didnt seem like anything was happening. Then he began to see the house. He began to see the furniture. He began to remember where he was.

Finally, he could take a deep breath, which he held for a long moment, before expelling his tension. 

SO it's with a sigh that he finally sags in his spot, and gives a little murmur. "what's going on..?"
