Where did my sleeper go?

So Nate has always been a good sleeper for me. It is something that all of my friends are jealous of. He slept through the night at a very young age (by the time he was as old as Graham is now.) He also was the kind of kid that I could just put him down in his crib, and he would go to sleep. Of course, on the flip side, he was also the kind of kid who did not want to be rocked or cuddled to sleep.
So anyway, about 2 months ago (right after the new year,) we put him into a toddler bed. He is 2 1/2 He never learned to climb out of his crib or anything, but we had asked for fancy sheets for him, and we got them for Christmas, and he wanted to have the sheets, but I wanted to save them for when he had a toddler bed. So we just went ahead and made the plunge, keeping the crib in his room anyway. So the transfer was seamless. He slept in the "Thomas bed" without any reservations. Sure, he now runs around his room when he is supposed to be napping, but he used to run around his crib while he was supposed to be napping. I don't see much difference. He can't open his door, and he never tries to. He was not the kind of kid who cries to be let out. All that has changed however in the last few weeks. It started with him saying "remember to stay in bed." I would say this to him every time I put him to bed after the 2nd day when he discovered that he could get out of his bed. So then he started to say it back to me. Then he started to say it over and over and over again, wanting you to say it back each time. He would get quite distressed if it was not repeated back to him. SO I would end up walking down the hall yelling "remember to stay in bed."
In the past few days it has gotten worse. He now freaks out about everything. It used to be that he would just freak out if his closet door was open, and then it extened to the lotion not being inside the closet. Now if his covers fall the wrong way we need to fix it. Last night we were called up like 4 times. Once it was because the pillow in his crib (you know, the crib that he does not use, and the pillow that he does not want) was not lying the right way, so that needed to be fixed. Then his blanket was not covereing all of his other blanket, so that needed to be fixed. I guess these are just his "cups of water."
It's just one of those things where we used to have it so good, and now it's just super annoying that he has regressed to this. Although, it can't really be regressing if he never did it to begin with. Oh well, as in all things toddler, this too will pass, and then he will be back to being the good little sleeper we all know and love.
Now if I could just get Graham to be a good sleeper too...
