Apparently Paranormal Options

Hello Everyone!
Wanted to ask i had an experience/appearance of a paranomal,
It looked like a smokey-cloud with color changes.
Any ideas?

Sorry for the low-quality description,
I saw it at my room, around 4am-5am. The duration is about 10-20minutes, I felt with heavy pulses over my body, especially my heart, I didnt feel scared after i recognized as something in my room,
The size of it, i think it was unstable in size, Because I was laying on my bed with my laptop on my lap, After i shut down my laptop i could see it at the end of my room.
I wanted to make sure i was not hallucinating, I could see it again and changing colors, So i tried to force self to sleep, but it was hard,i was covered with the bed cover and i still could see the smoke and color changing under the cover.
The colors changed from red to blue, and swaping.
It was a first time to see something like that and never saw it after!

Based on your other experiences, I'd say it was probably paranormal...and I'd again repeat myself in emphasizing how important it is for you to learn how to banish and to turn these things "off" since you're so sensitive to them...
