Abraham admits it was the confidence he needed.
"Obviously it is great to score a hat-trick and win the game," Abraham told the club's website.
"My favourite goal was the third, it was great link-up play and I managed to get into the box and Callum put it across goal for me to get the tap-in.
"It is an honour to play for this club and to score goals and get a hat-trick, it is what dreams are made of. Give credit to Luton, they are a good side, but we had to build our confidence back and go back to the normal routine of what we are good at.
"We know how good we are, results haven't been going our way recently, so we needed to come out and build our confidence back, and we have another game on Wednesday.
"Hopefully we will go into that game with confidence, try to get an early goal and try to settle early."
