you ni or Sama to mean 'like [insert thing]"

[rayman.the.one.and.only1_498570]

So I heard somewhere that you could use 'you ni' at the end of a sentence to mean something is like something else. For example: 「夢がように」　”Yume ga you ni" or "Like a dream." Is this right at all, I also heard that you could use the word sama to mean 'like' for example: 「夢がように」　"Yume ga sama/ like a dream"
So my question is which one of these is correct? Are they both correct? Which is more commonly used?

Thanks in advance- Yoroshiku ^_~

Firstly, I think the phrase is 夢のように…。
Secondly, 夢の様に also exist.
As you know kanji has at least two readings, in this case the kanji 様 is read not “sama” but“you”.
