This is what happened:

I went to sleep around 2am. I slept all the way to 10am. Then I was woken up for breakfast. After that I went to carry some logs into my cellar. Then I went back to bed. I had to do a lot of relaxation to get myself relaxed enough to fall asleep. At one point, just when I was half unconsciously watching these HI, my dad came to my room. After 5 minutes I went back to bed again, and fell asleep.

Hereīs the important part.

Around 1pm I just lied in a comfty position, I had prolly woken up just 10 minutes ago. Then I felt the SP coming, so I just kept still and waited. As te SP kicked in 100%, it was pretty easy for me to keep myself aware, I just told myself this mantra I canīt remember. Then bang, I went out of my physical body. Then I just opened my eyes. I did a reality check, damn, I was awake. So I lied down again, and this happened again. And again. I would say this happened about 3-4 times. It only took me 10-60sec per SP.

So obviosly, Iīm gonna use this discovery to WILD. I just need to find out what did I do wrong. Why didnīt I enter a dream?
I definately felt the SP (although itīs more powerful when Iīm really tired), and I saw some HI. I even felt exiting my body at one point. But every time I opened my eyes I was awake.

I guess that the cause could be this:
I didnīt wait for my dream to form. I just guessed that Iīm in the dream now and I opened my eyes. Dreaming or not, this results in me opening my physical eyes. Another thing is that I was too excited.
So I have to keep calm and wait for the dream to form around me.
