Is This a Dream?

My sister was at my home, and I walked into the kitchen and there was cat food ALL over the floor. I couldn't understand how it got there and I was cleaning it up as she walked into the hall to ask what was going on. I said I was so perplexed and didn't know how all the cat food got on the floor and then I realized it might be a dream, so I said to her: "I think this is a dream!" and she reached her hand out to help me stand up and said, "If it's a dream, you won't feel my hand" and I didn't feel her hand and then I awoke!
