Hello again, :)
Yes, I also sometimes got a little tired when I sent the project on jam (this usually happens at night XD), but it does not happen so often, so one time right?
And about music, I can advise an excellent place, this is a record library of YouTube, there are a lot of music and free of charge (those with the badge on the right need to be mentioned, and most of the music without a badge of mention).
I also looked a bit, and I found this kind of music: Spirit of the Dead (write in the search engine of the YouTube library, the search engine on the right)
If you want to search frightening music, try ambient
