When did you do this, right before going to bed or after waking up? What you experienced (strange feelings and sounds) was probably SP, sleep paralysis, which is normal when you try to WILD (I guess that's what you tried to do). It's what happens when you fall asleep, so your body won't hurt itself during sleep (though I don't know why there are hallucinations lol). You should just try to ignore SP when it happens and keep going, which might be hard sometimes because it can feel quite uncomfortable. What happened afterwards?
