Thanks Sugarglider11
I'll try not to be afraid next time.

I tried again after posting and also watched some pictures of a white palm beach, to help me see a dreamscenario, but this time instead of blackness, there were so much images that I could not focus on my beach and fell asleep before SP.

Woke up 5+ hours later (which is now), read a tutorial and try again.

It's really exciting to read all kinds of experiences here on the forum, I want that too!
