Why did namine put Sora to sleep

Namine put Sora to sleep because as he walked into Castle Oblivion (A strange castle that causes visitors to lose their memories) Sora lost his memories. Sora is the keyblade weilder. (the keyblade is a weapon that can entinguish dark creaturs called heartless and create Kingdom Hearts through them)He is needed to protect the worlds from the heartless and Organization Xlll (which are a group of nobodies trying to harness Sora's power to complete Kingdom Hearts to gain hearts of their own)He needs to regain his memories to remember his best friends Kairi and Riku and his goal to save the worlds.

To see what happened during the year that Sora was asleep, play Kingdom Hearts 368/2 Days for Nitendo DS and DSi.


True, but Sora could have just remembered what happened at the Castle Oblivion--which was created by Aqua on Kingdom Hearts: Birth By Sleep--but he CHOSE to get his old memories back. Since Namine is a witch that can control Sora's memories and those connected to him because Kairi was her other half and stuff, blah blah blah...I'll continue with this question later.

But I don't think the castle has anything to do with memories. It wasn't the cause of sora's memory lose, It was Namine. Otherwise the other organization members would also lose their memories. I also believe the reason sora had to be put to sleep was the fact that if he wanted his old memories back, The memories from the castle must be removed. He had to sleep otherwise if he had been awake he would suffer from having all his memories replaced all at one time. Kinda like how you are put to sleep for surgery.
