TL;DR conclusion down the bottom!
I actually had 2 LDs this morning, one was a DILD and the other was a WILD, both very short and both false awakenings where I couldn't see anything. I could feel though, I imagined myself getting a massage in the DILD (it was an interesting pleasure/pain sensation) and in the WILD I actually got up and reached out and someone grabbed my hands.
I think the blindness was due to a sleep mask I've started wearing. Perhaps a solid nose pinch reality check might have stabilised things and I could take the mask off or 'open' my eyes.
But the most interesting thing about it all was how I got into the WILD. It might help someone here out so I'll go into details...
I've come close to WILDs a few times this week. Vibrations, Noises, Hypnagogia, but I've never been able to fully form a dream. This morning though, as the visuals began to cycle I started seeing different rooms of a house, first a bedroom (not mine) then a tiled floor probably a kitchen. The rooms looked real but it was like tunnel vision and I couldn't feel my dream body. I realised that I could move my eyes though, and when I did, my perspective in the room changed. So I started rolling my eyes back and forth and it looked like I was spinning around in the room. After a while the dream solidified and I was able to feel my body. However I was blind and in bed again but it felt so real I was actually worried I had just woken up. I don't know why I didn't do a reality check, I clearly still need to build up the habit but this was when I eventually pushed myself up out of bed, reached out and grabbed an invisible dream character. I actually thought it might have been my wife back from work, we both fell back into bed and I woke up for real, no wife.
TL;DR
I was having trouble forming a WILD where I couldn't interact or feel my dream body. I tried rolling my eyes around, somehow the movement relative to the dream visuals helped solidify me in the environment, similar to spinning around or touching things.
