It's quite warm inside a blanket

What are you doing in this dark cell?
 I can't move, I can't change anything, I can't even make the cell more comfortable there is nothing here.
Well come out! Come with me, there are other places.
 I have tried that, and so have you- do you remember the Tower? But somehow I always find myself back here and this time I can't find the will to leave. I will just stay down here and see what happens.
