Entity Experience - Just Starting Out Options

Hello, I'm new here, and a novice in magick

This is my first post because I don't really know enough to contribute anything to the site. I've been looking for a good forum that I can look around and maybe get some help if needed. I am reading Magick by Aleister Crowley (the big blue one with 4 parts) Modern Magick by Donald Michael Kraig, and Condensed Chaos by Phil Hine. I started learning about magick when I was about 15, I stopped all progress for no apparent reason at 17, and am now trying to start up again at 19.

So that being said please take it easy on me

I had an experience a few years ago that I didn't and still don't understand, after I had been messing around with the Necronomicon (simon version??) I tried to evoke Asaruludu, Asarualim, and Lugaldurmah. So two weeks later after nothing happening, I wake up in the night to go to the bathroom,probably around 2 am. When I'm walking back to my bedroom and I'm a few feet away from my door I get a really strong sensation someones behind me, so I pause to turn around. Before I can something comes flying past my right ear whispering something inaudible, (just sasasasa lol that's kind of how I remember it) and I got that goose bump inducing feeling in your ear that makes you squirm. So it stops about 5 feet away from me and I see it is a human shape about my size that is completely shining white and the edges looks like some static electricity or something like that. It was all completely shining white, very very bright, brightest at the center of the chest, and the face had no facial features but a big fat black smiling mouth void of teeth and tongue. I noticed it had horns like a rams horns in the sense that they looked segmented (you know?) , but they were dull and brownish kind of dirty looking almost, and I thought to myself how weird it was that it would have such a brilliant body and dull horns. It was smiling and seemed to be very amused or pleased. I just stood frozen staring at this thing for a maybe 30 seconds. Then it turns, and bolts up the stair case, through the kitchen across the living room to the front door where it paused for a split second then it took off like the car in back to the future through the door and I felt a hard shudder in my chest like the wind was knocked out of, me but with no pain. (This is the hardest part to explain) While it was walking up the stairs through the house to the door I followed it with my eyes, just staring at the wall and ceiling, but I could see it moving around in my mind like I had mental x-ray vision.
I then went into my bedroom and went to sleep, it didn't really hit me until the morning that I had had a very strange experience.

I didn't tell anyone for a while thinking that people wouldn't believe me, then I told a couple friends and later my parents.

After this I stopped working with the Necronomicon and started reading and doing other things.

So if anyone can give me some feedback, any and all would be greatly appreciated.

**Sorry for the length of the post and if there are any grammar/spelling errors making it difficult to read.

soooo I'm guessing this was an insignificant experience where all that was happening was an entity was trying to make itself look a hell of a lot more important/powerful or whatever
