Weird Sensations/phenomenon In Meditation

[Torkys]

I did a 1 hour SDS sit today and I felt strange sensations. I would like this thread to be a list of weird phenomenon in meditation and their possible causes/effects.

List of sensations in my experience. If anyone has explanations of these, please let me know. If you encounter other ones or have similar experiences, please post them below: 

1) Subtle to heavy shaking

@Leo Gura already answered this one in this thread.

2) Gentle rocking of the body

The exact feeling described here.

3) Sound and feeling of a small bubble popping over and over again in the gorge (with varying frequency. In an earlier session, I had one pop per breath-cycle, it changed to 3-4 per cycle this time)

4) Tingling sensation and vibration in the body

If you have reached the vibrational state in astral projection, this is the exact feeling I felt.

5) Leg "freezing"

I have experienced this for the first time in this 1 hour SDS session. After my legs fell asleep, it started to feel like something is boiling inside of my right leg (outer leg, I sat in Burmese), but it actually cools the leg instead of making it hot. The feeling spread to my right calf later. 

All of this I have experienced. What do you think? What causes these and what are the effects of these? Please let me know the explanations for these and if you have other phenomena occurred to you that isn't mentioned in this post, post it below so you will receive your explanations.

@Torkys one time, reality poured through me and I cried tears of joy for days. I’m still mesmerized by the magnitude of love in the truth. “Flying” also comes to mind. The body sleeping while conscious is delicious. My most blissful meditation experience ever though, is no thought.

Just found this one.

Experienced Leg Freezing multiple times now, it is just the thighs falling asleep.

@Torkys Yes it’s quite usual in 1 hour + sittings
