Thoughts ?

Hey,

This is my second time trying to project and this is what happent,
First off all i was watching a video by lucidology to learn more about sleep paralyses
After that i got rolled up a blunt and relaxed myself with some music.

Then about 30 minutes later, (about 3 PM) i was lying on my back with my arms next to me (Not crossed) and tried to come into a sleep paralyses,
Ive heard that your body sends a message to your mind to see if your mind is asleep,(And you need to ignore that message to get your body to fall asleep)
So i tried to focus on that and after a while it feeled like i had a imaginary blanket over my body..

About a couple minutes later I started hearing noices (Like there was alot of traffic passing my street)
I was thinking that it couldnt be that busy at this time ( 3/4 PM)
Then i started to relax again and the noises where going away,
Thats where my visual started to get black and it felt like my arm was almost against my body (wich wasnt my starting position)
It also felt like i was looking in a different direction, while when I started the projection I had my eyes focused on the roof (Dont know if that makes any sense to yall)
After that it felt like i was in a cycle (Dont know how to discribe it differntly) And it felt like my body was rolled in a U form,
Then everything started to spin around, my focus slipped and I ruined my trance ..

Can somebody tells me if smoking before projection causes any trouble? And could anyone give me some feedback,
Thanks in advance ;)
