Hammer House of Mystery and Suspense:
Child’s Play (1986) by Val Guest

Being locked up in a room can cause panic. But being completely surrounded by an undestroyable wall, which over night rose around your entire house without your knowledge, and which prohibits every single possibility of air, light and escape, is more than a threat, and you might start to notice and question things, you weren’t aware for your whole life. Who is my child? Who is my husband? Who am I?

The entity (1981) Sidney J. Furie

When Carla (Barabara Hershey) gets beaten and raped by an invisible stalker, nobody doubts on her mental debility. The stronger she insists on the nasty existence the more obvious it gets in the eyes of the psychologists. A case for the asylum. But she won’t give up, nor does her invisible enemy.
