I think I noticed some vibrations this morning after around 6-7 hours of sleep, and going into a dream-like state didn't take much effort.
Edit: Btw without thinking I asked if this was normal, don't answer that, I know it's normal, I just meant I'd like an explanation of why it happens so easily xD
Think of it like a radio receiver. The cause of the vibrations is always there.
You are just tuning into the right frequency, allowing a kind of metaphoric resonance to occur.
They are easy to feel because because they are always there.
Remember:
We are not physical beings having an intangible experience, we are intangible beings having a physical experience. -Thomas Campbell

That mindset might help actually, the going-home feel might make it easier.
