Sleep Position for WILD

Hi there,

My first LD was done through WILD - it seems I can only keep concentration when laying on my back, where normally I lay on my front.

Does anyone else have to change sleep position to go into a LD, or do you just fall asleep as you normally would (but keeping concentration etc.)?

It's like I have different presets;
On my back I'm focused and in a hazy state, but I never quite reach the WILD :/
On my sides I lose consciousness but fall asleep pretty quickly
On stomach is bad for your spine so I don't do that anymore :P
