What is going on now?

Two weeks ago, my 8 year old daughter, who has been fighting a rare terminal illness, was placed in a chemical coma then frozen through cryogenics. Later that same week, my 6 year old daughter was diagnosed with the same illness. In order to study her tissues in early disease development, we made the heartbreaking decision to freeze my 6 year old as well through cryogenics. It has been hard losing both my children in one week, but we go and visit them like they are in the hospital. We put little cards and toys right by their cryogenic tubes. Do you think they can hear us when we talk to them? Do you think they can see us in their frozen state? They are frozen right by each other. Do you think they can see each other? Do you think they are dreaming in their frozen state?
