Ok, two or three times is no where near enough to get discouraged 
. I see posts just like these all the time, and it’s almost always asking about the same thing. Here’s what you need to understand: this may take time, lots of time. There are some people who are gifted enough to master it within a few days, but I’ve never met one in person. And even though I’ve had 1 or 2, I have not been able to consistently get them. Don’t worry about time, don’t worry about lack of progress, just do it.
Now, you sound like you’re worried you may not be doing it right, so let me help you out there. First, instead of just laying there waiting for HI (which you technically don’t even need to experience btw) try to count to help keep your mind focused. It can be good to count when you inhale, and say “I’m dreaming” when you exhale. Second, don’t move… at all. Checking to see if you’re paralyzed will ruin the entire process. It’s tempting, I know, but don’t do it!
One more thing, when are you doing this? If you’re doing it right as you go to bed you will have a much harder time as it will take at least 90 minutes before you hit your first REM cycle. Set an alarm for 5-6 hours after you go to bed and then try to WILD after that (you don’t have to completely get up like in a WBTB). You will fall asleep much faster and your chances will greatly improve.
Lastly, read these articles from out Knowledge Base. Better yet, visit the Knowledge Base in general.
WILD- A user friendly tutorial. This is great for knowing what to expect with HI.
The WILD FAQ. This will probably answer most of your questions and goes very in depth with how to do everything.
Best of luck, and let us know how it goes
