One thing you can do is assume a more energetic personality.
People in the modern world are afraid to do that, due to the psychosis accusations and possibility of having all psychic activity restricted by vile medicine.
If you can build up your energy by adopting or assuming something similar to a 'god form', you can build that energy all day long, even while you are doing other things. You can multitask. You can.
In my experience, simply wanting an astral experience isn't enough. You have to really want to experience it. On the flipside, we are already living in the astral! Physical Universe and Spiritual Planes all exist as a perception of the same vibration. You can do whatever you want in your own field, finding a way to hang on to your energy can be hard but it can be done. Build up your energy all through the day, then, when you relax at night, you can rip and shred the astral planes like a true born demi god.
How can I say that differently? Here...
- when you wake up, notice the sensation in and around your head, that feeling like, 'i want to go back to sleep'... your planar alignment is coming into focus, and by the time you get out of bed, your day has already been decided, so I'll say for now
- after you have fully woken up and taken a whizz and brushed your teeth, just go and stand at your bedside for about two minutes, just look at your bed and see if any sensations or memories of dreams start to surface
- as you are out the door to work, try and regain that phased energy flow and simply hold it all through the day, you can even defy ordinary physical laws if your kinetic phase is attuned to the baseline
Alternately, in your breaks, focus the technique, "Dark Bomb"...

No idea what a dark bomb is? I'll have to find the file. There are different types of dark bomb techniques, one is a shield, the other is a targetted offensive, and another still that enables slight mutations, endomorphically. You don't have to use dark bomb, you can just try and energize yourself.
I'll have to see how it goes for me tonight, earlier today I went for a walk and concentrated 'purification energy' into my solar plexus chakra. I didn't walk very far, but gleaned a sense of energy that had my thought overiding the schizophrenia, the Menace or Voice which is always stealing my time. It felt great. Perhaps you could try that as well, like a Purification Blast of some kind.
Oh! Here it is. In my mind, such a thing exists as a "Hyperion Beam". This does not come directly from the game, Pokemon, for Nintendo systems. The Hyperion Beam is not actually a beam that is projected or shot at anything. It is a system of ascension all of it's own type. What you do is...
- focus an incredible velocity, imagine yourself flying directly upwards at maximum speed
- keep working on that velocity, increase speed
- eventually, you will gain a hyperion charge
So it's basically about increasing speed. You have to watch out! Don't release the energy, but continually concentrate it, or just hold the energy. Almost immediately after increasing your velocity, you will notice visualizations popping up and feelings rising inside of you, like an excitement. You can and must continually charge the Hyperion Beam in order for it to work. Watch out for spontaneous combustion!! lol Really!! Just keep accelerating, in imagination, and it builds the hyperion charge for the beam. It's not a beam, it's an energy state. You might eventually be able to fly and certainly, you will run very fast if you are capable of running at all. Keep the pressure on, you can go in any direction and eventually the hyperion beam gets to be omnidirectional. At that point, you become a celestial entity, and will have long left the physical illusion.
