This phrase is from the film “The Unforgivable” 2021
Jenny is sick and her sister is talking with her
The sister says “You know, they heard you up all night again last night. Gotta go back on your meds”.
What does "hear you up" mean in this case?
Does it mean "Jenny couldn't sleep well and got up several times in the middle of the night" or may be "Jenny had a broken sleep" or something like that?
