I am in all honestly very confused about this, but I shall tell you what happened first before asking my question.
You know those mornings when you don't want to get up and you just lay in bed listening to music, or reading, or whatever you want kind of days (great days those). Well that is what I was doing this particular morning, just kind of enjoying the warmth that is my bed. I thought I heard Sparta so I sat up and looked around but didn't hear it again. I shrugged it off and lay back down. Then I felt a cat jump up onto the foot of my bed and lay down next to me. I know it was a cat because only a cat walks like that, (and its not as if this feeling is odd to me I have never not owned a cat). Eventually I just reached down to pet Sparta, (my cat who I think is on the bed with me), but when I reached to where I felt the cat there was nothing there. Instantly I sat up and looked at where I felt this cat. Once I saw there was nothing there the feeling faded a bit.
"Hey grandma where is Sparta?"
"She is outside. I let her out around 6am"
"Okay thanks."
I shrugged it off as my imagination and lay back down. About five minutes later the feeling returned in the same spot. Then it actually got up and walked up my bed and lay down at the back of my neck. By now I had turned my music off and was just listening for any sound. I didn't hear anything but I did feel weight and warmth. Seeing as it wasn't doing anything I just laid there until it drifted away.
So yeah... Most people that report seeing/hearing/sensing spirit animals have had a pet die recently, (last cat to die was over a year ago) so assuming it wasn't my imagination what the heck was it? I thought ghosts were supposed to make you cold, but this was hot. Well warm. It really felt like a cat was sitting next to me.
A few of my friends laughed it off saying I was being visited by kitty spirits. Mostly because I have come home several times and have had strange cats that weren't mine sleeping on my bed as if they belonged there.
