Dream invading spirits?

Since I'm moving stuff over from my old Xanga account to my new blogspot for dreams, I decided to post this entry on here since I feel it was more than a dream.

(August 26, 2004)

The first 'Dream' : I remember someone was trying to either threaten or convince me about something (or both) in a dark dingy place.
Then suddenly someone said "Oh yeah? Look at your cat!"
I then really DID wake up and looked at the foot of my bed where my cat was sleeping, suddenly he mumbled and growled in his sleep, and ran out of my room with a hiss. I spent the rest of the time with my blankets wrapped around me until sunrise it scared me so bad... then they came back.

The second 'Dream': This time I felt it more than heard it. I was scared and something made me wake up. I'm not even sure this one was a dream. But I woke up and the feeling of something... bad... was outside my windows.
Then I heard Drumming... three beats, pause... three beats... pause...
it continued until about four in the morning. My cat (strangely) stayed by my side and stared at the window with his ears flat.

There was a week or so in between these events... Nothing's happened since... but I can't be sure that it's finished.
If it does happen again I'll probably have my room blessed, that's the only idea I have. I'm wondering if I've got some ticked off spirit after me... though I can't think of any reason why I'd have ticked one off.
I do have a little 'sensitivity' when it comes to ghosties, but it's never been anything more than a glimpse or a chill... with exceptions I guess.
