Several weeks ago I woke up with just one word "лапидарно" (RU), I wasn't able to remember what it means, so I looked it up in the dictionary. I had never used this word and had had only a vague idea about the meaning. Today I woke up with the word "escaparate" (ES). I didn't manage to remember the meaning but when I looked it up I saw I had known it. My subconscious mind gives me little presents like these words :)
