Hi,
I've been trying to project now for a couple of months and I think I've come close but I'm not sure.
Hi there daytona955

Welcome to the Astral Pulse... let's see if we can't try to help you a bit.
I've had spontaneous sleep paralysis since I was about 10 but I have always shook myself out of it due to been scared.
As I mentioned to someone else earlier, there's nothing to be afraid of in Sleep Paralysis... in this case, you're your own worst enemy.
When you encounter it, just stay relaxed and calm... try not to think about much.
I was only when researching SP that I found out about the link between SP and AP, so I have been trying. I think I managed to get my hand free one morning and I could see straight through it! But I'm not sure if I was just lucid dreaming?? I could also see my eyelashes, but not blurry like when you squint your eyes, they were all in focus and perfectly formed. Is that normal??
Perfectly normal.

However, instead of trying to move a limb... try to roll your entire body! Just try to physically roll over!
If that doesn't work, just visualize yourself as a giant balloon floating upwards towards your ceiling.
To get to the point, I really want to believe in the Astral Plane, so if it exists, what is the point of this physical one?
Some people, such as myself, believe this physical reality exists to EXPERIENCE things in. There are some things you can only experience while being physical.
Why is the Astral Plane so unbelievable to other people if they are like minded spirits?
Because we're taught and conditioned to believe that if you can't physically see it, touch it, taste it, smell it or hear it... then it doesn't really exist.
