My hamster mysteriously dissapear!?

last night before i felt asleep i saw my hamster playing on her cage everything was normal at night time nothing unusual until this morning when i woke up & when to check she was okay had water & food .. she wasn't there & it wasn't any sigh of her not like other times she couldn't of scape because her cage was close i ask all the members on my family if they had taken her out but no one knew a thing we search the house all over but she is nowhere to be found .. the strange this that scares me is that here cage was close & its pretty impossible for a hamster itself to scape & close the cage... another weird things being happening like a remote control disappearing, money & jewelry but nothing was as important as my pet because we thought a person had stole the money & jewelry & that we just had misplace the remote control but my hamster? =\ its pretty weird.... any explanation?
