Ghosts, Demons and Other Paranormal Beings: Real or Fake?

Ever since I was little my mom (before she passed away) told us kids stories about seeing ghosts and playing with a Wiji Board. She said she threw the board in the fireplace and it screamed at her. Not sure what to believe about that one...
But I've seen my fair share of things I can't explain, and no one believes me.
At my old house I got up to get a drink of water and went into the kitchen, but when I passed my mom's bedroom door there was a little kid wrapped in a blanket standing there in front of her TV while she was asleep just staring at it. My two little brothers were in their room and their heads were pretty much bald, but this kid looked about 4 or 5 and had hair down to it's ears. I couldn't tell if it was a boy or a girl. I flipped and ran back into my room. lol
Just recently in my new house I moved into with my fiance, while he was at work and I was settling down for bed a kept hearing weird banging noises in my kitchen, then a dark shadow of a tall man went across my wall. It was dark in the room except for my little lamp that we use as a light to see when we need to get up. My cat started FREAKING out, hissing and growling and chasing something around the room. Then the night light just turned off by itself. I felt so cold, and it was like something was watching me... I wouldn't have been so scared if my cat hadn't been spazzing. I hid under the blanket until my fiance came home on his break.

Any opinions or ideas about what this could be? The most recent thing reminds me of the movie Paranormal Activity. lol But why would a demon want to bother me of all the people in the world? O.o

Yes it's all 100% real, I have always seen them spirits and ghost on and off all my life, one beautiful spirit came to me for four years, she was the only one that would actually talk to me, and communicate in other ways, sometimes she would come within my dream to give a message. I have seen as many as five to six different one here where I live, most just come near, but the woman is always so nice to me, she I believe is my spirit guide, I seen her last about six months ago, I seen a dark shadow man just three months ago look down at me when I started sleeping with my sleeping mask on, I sense he was wondering what it was on my face.

Whoever they choose to bother is a random thing. The truth is that they were expelled from the heavenly realm and were hurled down to the earth; they know they will be  destroyed very soon. For this reason, they have come down here "having great anger." -Revelation 12:7-9, 12.

Since demons appear to us in several different shapes, some people are misled into thinking that ghosts exist. But the Bible says that it´s not possible for dead people appear before the living. When we die, we cease to think; we cease to exist. -Ecclesiastes 9:5, 6, 10; Psalm 146:3, 4.
People who were involved in demon-worshiping secret societies will be able to tell you that the supposed "spirits of the dead" are just demons in disguise. Research the story of Roger Morneau.

Therefore, shadows, shadowy figures, translucent specters of human beings, babies, a man with a hood, apparitions of 'saints' etc. are all different forms demons take to mislead humankind into thinking that human beings have an immortal soul.
They also mislead people into believing that extraterrestrial beings from other galaxies and planets exist and are visiting us. This explains their appearing to some people as grays, reptilians etc. They also like to take the shape of animals from time to time. It´s all part of the their "lying signs" and "unrighteous deceptions." They´re the biggest liars, impostors and deceivers.

The Bible identifies them very clearly:
Ephesians 6:11, 12:
Put on the complete suit of armor from God that YOU may be able to stand firm against the machinations of the Devil; because we have a wrestling, not against blood and flesh, but against the governments, against the authorities, against the world rulers of this darkness, against the wicked spirit forces in the heavenly places.

And 2 Thessalonians 2:9-12 states:
But the lawless one’s presence is according to the operation of Satan with every powerful work and lying signs and portents and with every unrighteous deception for those who are perishing, as a retribution because they did not accept the love of the truth that they might be saved. So that is why God lets an operation of error go to them, that they may get to believing the lie, in order that they all may be judged because they did not believe the truth but took pleasure in unrighteousness.

There allot of theories out there of what this ghost could actually be, but of the one thing I know is that if you define that their demon's then they will be demon's. We subconsciously create our own reality in a weird kind of way but that's a story for a another day. From the words of a leading spirit medium(not me) you bring what you reap, meaning that if your destructible and negative that's what you will attract. So really the question is, what are you subconsciously letting in to your life? Are you living in fear and letting this things get the better of you? or you a curious and care free?. As far as what they are, it seems to me that they are withing another dimension, if you talk to a 2D being they cannot see you but you could see them.
