There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Neo-Sindarin: I’d retain the verb ᴺS. lor- for purposes of Neo-Sindarin, but with the sense “sleep, slumber” only; for “dream” I’d use N. oltha- (Ety/ÓLOS). This neologism has likely been floating around for a while, but it was first suggested to me by Elaran.
