Hello i had a dream that my family was judging me...

Praise is to Allah. We seek refuge in Him. He is not misguided. He who is guided by Allah no one shall mislead him. And no one shall guide a misleading person. I testify that there is no god but Allah, who has no partner and that Muhammad is His servant and His Messenger.
My honorable customer, This dream is from Satan as he wants to frighten you, as the dream interpreters consider this weak dream not a vision. As God says in Quran: It was Satan who suggested to you the fear of his allies. Do not fear them; fear Me, if you truly believe.
Therefore, it is recommended for anyone who sees such a dream to spit on his left side three times and seek refuge in Allah from the accursed Satan. He may say” O Allah, I ask you the good of this dream and I seek refuge in you from its evil because these dreams is from Satan
It is clear form Satan and you have to be closer to Allah and increase duaa and read Quran before sleeping. Because what the sleeper see whether a true vision or a fear or manipulation of Satan
Jabir reported that there came to Allah's Apostle (ﷺ) a desert Arab and said:
Allah's Messenger, I saw in the state of sleep as if my head had been cut off and I had been moving on haltingly after it. Thereupon Allah's Messenger (ﷺ) said to that desert Arab: Do not narrate to the people the vain sporting of satan with you in your sleep and (the narrator) also said: I heard Allah's Messenger (ﷺ) in his subsequent address: None amongst you should narrate the vain sporting of devil with him in the dream
I ask Allah to guide you to what He loves and pleases, and to go beyond the evils of your deeds and to enter us and you in His mercy.
