I had a WILD last night, through accident really, I gave up on trying, and it just happened in the end, but its unreliable, and was quite unstable, so I need to master the correct technique (:

When I enter SP, (which happens quite easily to me when i first go to bed, and therefore I assume when I do a WBTB, although this morning it proved difficult.) My heart races, I begin to have difficulty breathing (seemingly) and need to swallow alot, and this all often results in me losing the SP
I do get HI, usually to the point of some vivid memory footprints and occasional sounds.
Please can anyone help me out here? I know I have to relax, but thats easier said than done. (: Ty in advance.
