Wes Morgan had given Forest an 86th-minute lead with his first goal of the season but in the final minute of normal time, Danny Haynes pounced for an equaliser.
Davies said: "I always thought it would be a tight game, maybe decided by one goal so I was disappointed that we conceded so late in the game having taken the lead.
"It was a soft goal to concede because our two central defenders had been excellent up until that point but we were beaten to the ball in the air and then caught ball-watching.
"I'm not complaining because we got a draw at Cardiff last weekend with a last-minute goal but it was a pity that we switched off.
"I've told the players that although we lost two points at the end it could prove to be a crucial point by the end of the season. The draw keeps us moving forward and maintains our unbeaten home run but I know there's still a lot of hard work to be done here."
