I believe when we intent to absorb energy, we are like a radio that channel a particular style of energy.
I highly doubt we can actually absorb "neutral" energy. We absorb energy that comes a source and we flavor it with our intent.
My experience is.
Air elemental power makes me feel like i'm Peter Pan. I'm floating in my room and some for object around it. Laughing noise are around. Smell of daisies/lavender. Feeling of spring wind.
Water elemental power is like being underwater (lol) to me. It smells like rose/jasmin. It feels like letting go. My room is like drowned, bubbles comes on the surface.
Fire elemental power in my experience feels like become a giant/a dragon/a dragon slayer (yeah both sides, depends on the intent) it exploded my room. I'm powerful. I hold a sword. Smell and taste of pepper.
Earth is like being in mine. With crystals/gold all around. Roots all over my body, dirt and diamonds mix together. My room is heavy. I have the taste of dirt in my mouth.
Akasha is like being in a church with grass all around. The roof explods and a shinning light comes from above. Smells of frankincense.
When it comes to a feeling, i base on which element makes me think of the intent (not necessary through correspondances) but common sense.
If i want to refresh my mind/spirit, i will think of "being fresh". I will focus on a meadow, clean drying clothes, smell of soap.... And i will see the energy swirling around me as huge bubbles. It's clearly a mix of water and air elemental power
