My first ever attempt was very underwhelming, but it's an important part so I will include it!

I listened to a lot of subliminals for shifting during the day and when it cane to afternoon I found myself in a moment where i would have the time to try.

I used a guided meditation of 10 minutes, I was laying completely still on my bed. After the meditation I very slowly started counting in my head from 1 to 100. Every 5 nymbers id say an affirmation in my head like "i can shift" or "I am shifting"

When I got to abou 70 my limbs started tingling and at  80 I lost any feeling in them. They also began twitching randomly and very subtly. At 90 my heartbeat was racing faster and faster. Through all this i was still calm though, its important to not fear the proccess. I could feel my entire body tense a bit, i notices how i was sortof lifting myself up, without being able to stop it.
All I did was keep counting.
It was getting brighter so i tried to focus on the light, imagening i was entering it.

Sadly, when i reached 100 i relaxed and most bits stopped, however, when i tried to move and open my phone, my arms were limp and they felt weak.

I might not have shifted, but its rare to do so at first and the fact that I git any symptoms at all makes it worth it!
