what did Daniel do in chapter 8 of the Bible?

In Daniel chapter 8, Daniel has a vision of a ram and a goat, which symbolize the Medo-Persian Empire and the Greek Empire, respectively. The ram, with two horns, represents the Medes and Persians, while the goat, with a prominent horn, represents Alexander the great. The chapter also foretells the rise of a smaller horn, symbolizing a future king who would oppose the holy people and cause desolation. Daniel is troubled by the vision and seeks understanding, ultimately receiving an interpretation from the angel Gabriel.
