The Trotters avoided the drop last season after picking up 11 points from their last five matches and although they are five points clear of third-bottom Newcastle, Megson is still looking over his shoulder.
He told the club's official website: "Last year, after we played Aston Villa away, there was a coming together of supporters, board, staff, players - everyone. It just happened and it was incredible how it was done.
"It had a massive impact and we took 11 out of the last 15 points.
"Although we are better placed now than we were at this stage of last season, we still need that coming together and common goal of everybody singing from the same hymn sheet."
