Ball python bumping top of cage?

[reggi-BP]

My ball python is roaming her cage a lot. She often times pushes the top screen too. I can describe it as she sticks her head all the way up to the screen and goes backwards until you can see her belly, falls back down and repeats that over and over again. Is this due to stress? I have not been handling her at all but she wont stop. The temp are around 90-93 on the hot side and cool side is 79-81

NO ITS NOT STRESS. mine used to do it all the time, i though she was trying to escape. but i have talked to people about it, an they said she was just exploring. an if shes going up to the basking light its to get some sun. is she new to the tank?
mine did it all the time, an my mom hated it but its normal.
