Hi there my friend,
First of all, it would be very helpful if you do a WBTB(wake back to bed) before performing a WILD. If you do a WBTB, your body will be more relaxed the time you perform a WILD. The reason why your eyes are twitching every-time it's closed is because it's been exposed to light for some amount of time. So it's either you stay away from light for 20 minutes before WILDing, or WBTB before WILDing. Hope this helps and feel free to ask more questions
