I couldn't place the setting, but the carpet looked like mine.
There was a hallway.
There is an intersecting hallway
There is a chair on either side of the intersecting hallway, right in the middle.

There was also a CB radio being broadcast.

I was being cornered and trapped.
Two people were trying to get me, one was Richard Dean Anderson.

The CB radio said something about kangaroo rats being a threat.

I was some sort of infected kangaroo rat.
I started jumping like a kangaroo. I don't know if a kangaroo rat jumps.
One was to scare me out of the corner and the other one was to capture me with their hands.
Richard Dean Anderson was the one to scare me.
I jumped up high and poisoned the other man.

I was clearly an actor. I "poisoned" by way up jumpng on the body, making a sucking sound and doing something with my hands. I didn't puncture any skin or do anything that is considered a method of poisoning.

I jumped to the other side of the hallway.
Richard Dean Anderson approached me.
I jumped up and "poisoned him".

I then started walking through the main hallway.
My thought here was: Jesus, this carpet needs vacuuming

The CB radio came back on. The voice was in a panic. They wanted to know if the team was all right, asking if there were any survivors. No one, of course, replied.

I turned around and walked back.
The slumped body of Richard Dean Anderson now looked like a sleeping body of my cat, Abagail. I touched the body on it's side and it was Abagail, my cat. She woke up.
