grammar question, again

Should I say/write:
1)
I was hid OR I was hidden. Does the first include an implicit reference to another party who hid me? Is the second completely neutral? Such that "I was hid from sight" and "I was hidden from sight" have two different meanings?
2)
Similarly, in the cases of "I was freed of his clutches" and "I was free of his clutches," is the meaning different, the first implying a something which did the freeing. Or can they both be neutral? Or is one maybe incorrect?

Thanks for the help
