my daughter

I have always believed in the paranormal-ghosts/spirits etc and i have always suspected that aliens do exist and even visit earth but for some reason i have always taken alien abduction “stories” with a pinch of salt so to speak. However there have been some odd incidences lately that i had until now attributed to a spirit of some kind. ( I have experienced paranormal things from a very young age such as items moving etc).  Lately there has been a lot of this but what is alarming me is that i do not think its spirits after all after a couple of incidents regarding my young daughter who has only just turned 7 years old. For the last few months she has become very scared of the dark. Even though she now sleeps in our bedroom it has not stopped her being scared. She  is very anxious about everything, household security, me being late to pick her up from school etc. I was worried she was depressed about something. The other night she showed me and her dad a drawing. It was a star and very inticrately drawn. Around it she had drawn two other planets. I asked her what it was and she told me that at the top of the star were the aliens, to the right was the bad planet and at the bottom was earth. “The bad aliens are going to the bad planet and then they are coming for us.” I asked her if they had been talking about aliens at school and she said ” no i was looking at the sky and the voice in my head told me”. We were a bit taken aback and i put the drawing in my top drawer. We didnt think too much more of it but Last night she again kept calling out to me saying she was scared. I kept telling her there was nothing to be frightened of but she insisted that there was someone standing in front of the bedroom door and that the “dust was lit up red”. this morning i asked her all about it and she told me there had been a loud noise like the sort of thing a road sweeper lorry makes. and a woman she described as a witch. she was old with a green face and black hair. I asked her how she had a green face as it was so dark at night and she said it was because she was lit up with the small red lights that were also over her. Normally i would of assumed this was a nightmare but after seeing that drawing  a  lot of my daughters fears now seem to make sense. Is 7 too young for this. Could it be an over active imagination. I just dont think it is. After reading some of these posts im astounded by some similarities to her experience. This is 100% geniune and i would really appreciate some advice. Sorry for rambling on a bit.
