Real Living Nightmare

A young woman named Rachel, soaring in her mid-twenties, is going through a rough patch in her life. Between depression and anxiety, her nightmares show her a horrific hint of reality in what she's going through or what is coming her way.
One stormy night, she starts getting random texts from an unknown number. First, it starts out as someone trying to scare her; then the texts become very clear that the person texting her is in the house.
As things start to get more real for Rachel, the intruder keeps torturing her.
Is the intruder trying to give her a message....or something more sinister?
