No. Deaton was overwelmed by his psi connection to Valack - that's what made him blackout.

Presumably - Lydia was able to draw him back from the vision he was having either by Banshee whisper or scream.

Peter didn't go into a coma because he could handle the connection - but he screamed because whatever Valack showed him was terrifying.
