Astral Projecting tips for tonight?

Hey, so I tried astral projecting last night.

So I laid back, closed my eyes and began to visualize myself looking down at my room. After a while (15-20 minutes) I began to vibrate (pretty intensely), felt my heart beating extremely fast, and oddly enough felt my bed shaking I felt my eyes begin to move and felt like I was beginning to roll around. Kinda. I kinda freaked out when I stopped vibrating and felt my bed starting to.


Firstly
How the F*** can I calm myself down when the body vibrations start. I kinda had an anxiety attack last night because I did not think anything would actually happen. It's kind of hard to just "ignore" it when it feels like I'm about to have a damn seizure

Secondly
I'm going to try the rope method. Where I visualize a rope hanging from my ceiling and begin to imagine myself climbing this rope until I am out of my body. Is this a good technique? Any tips on how to make it work better?

Thirdly
I have a hard time keeping my body still while sleeping. The corner of my eye tends to open during the (REM) or whatever's going on, and I begin to see the crack of light from the corner of my window appear. I then adjust my eye so it will close and am like "Sh**, I just moved." Also, my mouth tends to get dry and uncomfortable when I do this. I find myself "gulping" frequently while trying to project. Should I try to stop this little movement?

Lastly
Say tonight, I do achieve projection. What's it like when you break through? I've read that the vibrations mean that you're over halfway there, so what happens when I get that light feelin, vibrating? Will I just "snap" and be looking over my body? What's the transition like?

I usually become very relaxed and tingly... Like last night I tried this, and I felt like I was lifting up, but realized my hands were lifting too, and was like "Sh**, body's moving."

Please share any tips on how to help me project.
Happy travels
