Oh yea I totally forgot that "vivid" and "lucid" have got almost the same meaning as well... haha sorry about that. Lucid dreaming has probably coined me which is why for me there is this distinction between vivid and lucid haha...

You are right. Vivid means "lebensnah" which means "close to life" or "lively". However the other one is not so correct. Your translation for lucid ("einleuchtend") would be something like "obvious" or "plausible" in English. However the translation of "lucid" in German is more like "clear" or "distinct". Anyway.... let's just get rid of this confusion xD A lucid dream is a dream in which you know that you are dreaming and a vivid dream is a dream that feels life-like and is full of sensations. That's all we need to know, right?
