"I'm sorry, but do I know you?" said the kitty

Apparently my cat is having some very Memento moments. Granted I have only been her human for . . . well, less than 36 hours (though barely that)so it makes sense for her to not be TOTALLY adjusted - but she seems to know who I am most of the time. Or she did until I went to bed and then when I could not sleep she was excited because I came out of my room, BUT then when cold I put on a sweatshirt and kept the hood up which apparently turned me into some sort of a monster. She was scared! I didn't realize it and it was not until I removed my hood that she began to like me again. THEN I went back to bed (some hours later) and when I again woke up she was on the stairs. I didn't turn on the light so apparently she didn't recognize me (again) and so she ran down the stairs and in the dark I could see her turning back to me and then walk/running backwards. Finally she scrunched back and it was like she was recoiling! It was sad. Then she tried to curl up with my computer and now she is missing. Well, she's not, but it's dark and thus she is out of site.
