Dream about seeing hell from far

[Muslima_]

Assalam o Alaikum I had a very scary dream today. It was actually a dream within a dream. I saw that i am in a car with my deceased grandfather and he is driving. I saw a mountain from far which looked like a VERY TERRIBLE place. It looked exactly like hell , there were people being tortured there. That is all i saw and i asked my grandfather who they are and he said those are jins. I woke up from that dream (still in a dream) and i remember telling my young brother about this dream of seeing hell.
I am extremely scared. Please pray for me and can anyone tell me what i should do?
I offer my prayers alhamdullilah, i try to recite a surah of quran, i fast in ramadan, and try to do charity as well, and i have performed umrah too.
I occasionally get dreams where i am reciting quranic verses and i fear Allah SWT.
I know i am a sinner too as we all end up sinning but i do not want to be hell, astagfirullah.
Please help and guide what to do? Should i do sadqah?

Assalaam 'Alaykum sister

Forgive me for the questions. Was there any message in the dream? Was your grandfather a good man as far as you can tell? Is there anything else you remember?
