hey crashyy,
First of all you are entitled to your own opinion and I respect that, but really you don't have nothing to worry about. I'm not here to change your beliefs but i'm afraid the only thing on your list that is actually possible is UFO's everything else, in my opinion, is crap and has know scientific evidence what so ever. I don't even though why you associate it with lucid dreaming because it is a scientifically proven and studied a phenomenon. Also all you were experiencing while you were having a WILD is Sleep Paralysis and is again is scientifically proven and in short all you were experiencing was a hallucination because you were in a pre-sleep state. Commonly hallucinations are ghosts, demons, aliens, beings, entities, shadow persons etc... Finally about you not being able to have lucid dreaming because of you schedule, im afraid I can't comment on that because I'm only 15 but there are many other adults on this forum that can tell you what they do to fit it in to there time.
Again I can not stress enough that i'm trying to convert your opinion on these things but i'm afraid you can't argue with the facts.
Hope you have a good day/night

Btw please don't give up lucid dreaming it's amazing!!!
