What is going on!!??

So Pickles has been acting very odd the last few nights she normally comes out has a free run of the sofa for a bit then she goes in her playpen or ball but lately she seems to be in a real pickle!

She is very good with her timings and likes to come out around 8 she will sit on her bendy bridge close to the door of her cage then jump into my hand! Will have a quick cuddle and some whisker kisses as we are walking down stairs then all of a sudden she will go mad! She will run trying to dive off the sofa so I'll put her in her playpen she won't touch and toys treats she will just try and frantically get out she will climb into her ball but again won't stay in there even when I let her have free run of a hallway she sits by her door and scratches until I open it to take her back in!
She is eating and drinking fine no lumps bumps etc did a health check
Any one have i ideas what is going on as she seems to be in a real PICKLE!
