Injuries have dogged the American this season which has seen go in and out of Thomas Tuchel's side.
But a recent return to form has seen the 22-year-old score three goals Chelsea's last two league matches.
Writing in the programme for Tuesday's clash with Brighton, Pulisic said: "I think it all has to do with confidence and the way you're feeling in the moment. Streaks are definitely something that can be seen in a lot of different sports.
"I kind of went through one at the end of last season, I felt, and I hope that I'm catching a bit of fire now. I think it's definitely something – it's just a confidence thing where you see one ball go in the net and you're feeling good about it, then things just seem to come more naturally. I think that's really what it is.
"It's been a tough year, for a lot of reasons. Obviously, having injuries has been tough because I've been doing everything I can to take care of my body, and just try to be right for every game, and it really does hurt when I can't be out there to help the team. But I'm feeling good and healthy now, and I just want to do everything I can to keep it that way.
"I love this part of the year, when things get really important and every game can have a big influence on your standing at the end of the season. It's the best time really, when everyone focuses up and the games are usually really good."
