Question

Particle が and に in this sentence below
朝、まだ寝ている時、友達（に）来られました。

Why does the context above use particle に instead of が?

Answer

に来られた (に + passive verb form) usually also conveys a dissatisfaction towards what happened, so in this case the visit wasn't welcome. This is very common structure in Japanese.

If you said "朝、まだ寝ている時、友達　が　来ました", this would just be a neutral "... my friend came over". and "朝、まだ寝ている時、友達　が　来られました" would have the same meaning but in this case the passive form would convey higher politeness level towards the friend. Another example of this usage would be: "先生がこられました” the teacher came"

Answer

こんにちは。 「来られました」 is a verb in the passive form. When we use the passive form, the person from which the action is taken is pointed with に。 Another example: 私は　お母さんに　しかられました　I was scolded by my mother.
