reincarnation? wtf!

when naruto woke up he realised he had memories which had not been there.then he realised why he had headache midnight.then he remembered what had happened last night.

the previous day when he went eat ramen as it was his birthday,it was also the day kyubi or the nine tale fox attaked konoha.so after he ate there were drunk people chasing after him so he went to the mountain behind the hokage rock.

there wene he went to sleep he felt a something or someone in his head.then he felts that came to take over its body.but did not succeed and then he got headache and fainted.

when naruto realised this and searched though his memories after half an hour passed he got to know what happened.
