It is a tense which shows that we are in the middle of an action.

What is Past Continuous Tense?

The past continuous tense means that at a time in the past we were in the middle of an action.

We use the continuous with actions. We do not normally use it with state verbs. For states we use the past simple.

When we talk about present or the past we use verb forms to say what is happening now, what happened yesterday and so on?
