I'm trying to find a word that better describes the manner in which a person walks / moves across a room after receiving stunning news. The person is mentally absent and deep in thought processing the information.
I found worlds like amble and saunter that imply a slow walk (would certainly apply here) but they seem to connote a relaxed emotional state. Do either of those words apply here? Is there a word that does?
If not, any suggestions for concisely conveying that type of walk?
