Has your 'vibrations' changed?

[Daredevilpwn]

Hey guys. Those that feel 'vibrations' when you do DEILD or WILD. Have they ever changed? For me when I rarely remembered to do DEILD I felt vibrations but they felt just like being electrocuted but without pain but no strange sounds. But yesterday I decided I wanted to get good at DEILD. So I wake up a couple of times managing to be still. The vibes usually kick in instantly for me but not this time so I go back to sleep. Then I wake up from another dream. I feel a slight tingle I know this is it. The tingle then goes to full on vibrations but I also hear this loud sound. The best way to describe it is like a train getting a slow start but then progressing to max speed and volume. It sounded like that. Although I didn't get scared and managed to enter a dream I still found it odd that the vibrations would 'change' So has you 'vibrations' changed?

All these things are just HH, hypnagogic hallucinations. Just like something you're imagining they're bound to change both over time and while you're doing it. Personally I never feel vibrations but I do get a fair amount of HI (hypnagogic imagery (HH only with pictures)) and they often change. If I don't pay attention to them they often change quite radically but I normally like to play around with them .

Agreed, exploring the NREM stages can be quite an experience. Supposedly this stage is when we are most connected to our subconscious.
