Lol yes totally normal with the work youre putting in. Congrats you're advancing. I can feel the will power of how bad you want to succeed all the way over here. Remember to take it easy, you do not want to shock yourself or burn out. The best thing is to stay constient and to keep cleansing and doing protection too. Itll help keep your chakras stay open and prevent attracting bugs. As your mind Increases in activity void will be important too.
When we free our soul, our souls turn to light. Sometimes light can attract unwanted things so protection is crucial too. Balance is key here, but you will also take notice too on how much more powerful you will become, how much more youre advancing. You'll begin asking yourself sooner or later in shock if that actually happened. If it's not already.
The tired sensation comes from the blissful feeling of each chakra. The feeling of the energy flowing through us is enough to take us away even. The deeper you get into this you'll see yourself, the endless potential of what can be. The feeling of the energy as it increases will induce your brain more closer into theta brain cycles which explains the tiredness. After a certain point after your head does drop, instead of picking it back up to get back to meditation you'll have projected out of your body if you keep it up.
"A trance feels like: Everything gets quieter and you feel like you are in a much bigger place. There is a very slight humming feeling in your body. Everything feels different. It feels a bit like putting a cardboard box over your head in the dark, you can feel the atmosphere change. It's like everything goes fuzzy or slightly blurred. Any sharp noises, while in trance are painful."

I've done it myself without realizing before. I got so use to picking my head back up and reminding myself to meditate and started stretching and waking back up to keep going...that eventually I hit a point I didn't even know I fell asleep. I just kept going and ended up in other places. It's also happened when doing the rituals for the gods and some RTRs. I've gotten visions from the rituals before when the energy has carried me away.
I hope this helps!! Keep up the great work and continue to move more wiser than you did the previous day, everyday until you've mastered this path!!!
HAIL SATAN!!
