Mood swing?

Hi there, I have a lovely pup of 5 mths. He has always been active and playful, but last week, he began to show signs of uneasiness, he refuses to play and all he wants is to sleep in a most unreachable corner.(like hybernating) Nothing I can do to lure him out of his corner

But he will come to me when its time for his meals. Does anyone has the same experience?? I am worried sick about him. This behaviour will last for about 30hrs before he is back to normal again.

He is in one of his mood swing again today. What should I do/or not do?? He sleeps so much that he does not even drink or pee for many hours. How can I get him out of this? :-( Does it have to do with him not been neuter yet?
