Your recall can be improved if you are aware of yourself enough to wake slowly and remember the experience as you wake. You can get total recall by doing this.
There's so many different environments to experience in the non physical (NP) that fighting isn't normally a good thing if its out of sorts for the environment. This all depends on the reason for the battle. If fighting is the only way to solve the issue then so be it, you know this expectation though.
If it's saving locals from some terror and you succeed (a must do) then it may be a retrieval or a test of your mettle. That said, if you were only following a storyline with little self awareness, it will be a symbolic dream with messages for you. These need to be interpreted with the key characteristics and how you were feeling during the experience.
The top of the head thing can take many forms, I'd guess its an individual sensation. If its energy related or similar, I'm unsure, there's something going on. The thing that is apparent is everyone who has had this has progressed somewhat further into more challenging experiences.
After my first encounter I started to have clairvoyant dreams and a few years later retrievals started to increase in number and complexity.
Work on your recall first, the slow wake method is hard to do when the time up call is pulling you back. It can be done.
For an example of the details you can recall and a good experience.

Hello. Yes, I always often get to remember most parts of my dreams clearly whenever I get to wake up without being in a hurry; such as being woken up by an alarm due to the need to go to school.
Oh and thanks for giving insights about this Astral Battle that I had. As for what I felt during the experience; another detail of what happened during that dream (or Astral Projection experience?) it actually all feels very real, during the time I was gazing at the lake from the sky, I could feel the cold, wet and misty texture of the clouds to my skin, and then to walking around the mountains surrounding the lake, meeting some locals, sitting on a chair and chatting with... other 2 or 3 people who seem to be females, and I have a feeling that I know them... anyways during that time, the giant burning rocks started to fall and I got annoyed since we were relaxing there, I also felt the need to stop the one causing those rocks to fall since the people will surely get injured if I don't (and they are already panicking that time too) so I charged into battle, and I think the other 2 or 3 people I was talking to that time were helping the people get to safety.
During the fight, I actually felt different, from the feeling of wanting to stop the being causing the rocks to fall, when I was in front of it, I was kind of in a "wobbly" kinda feeling, or a bit confused, since I never seriously fought anyone in life, even until this point, and even during Taekwondo Sparring sessions/competitions, I always hold back and is always afraid to harm my opponent. Anyways, so during the battle, this dragon-like thing was getting ready to swing its spear to me, I panicked a bit since I don't know what to do, but then I heard this voice inside my head telling me to use the Four Elements to summon spears made out of it and attack the dragon with it much like a continuous-fire energy bolts one can do in the Astral Plane (and as Robert Bruce described; one of the easiest form of attack to do since you don't have to focus too much on the form, unlike an Astral Sword), well it did not do much damage, but I managed to dodge its attacks, the battle seems to be going nowhere since, for some reason, the Elemental Spears I was firing at it does feel kind of weak, it's like an energy construct that is very weak, it lacks some sort of solidity, and I can only attribute it to my not-so-strong willpower back then as well as weak focus, so then the voice in my head told me to summon two swords (I was actually crafting them from Psi Balls back then and visualizing them to being imbued with Light Energy, then the other one, with Elemental Energies), and this voice told me to combine the two swords, so yeah, before the dragon-like thing's spear managed to hit me, I was able to slash him first and I won the battle.
That's mostly the full account of my experience back then. I never had any dream like that after all these years... or so I thought, but recently around 2-3 years ago, I seem to have another AP experience (as my teacher friend and mentor validated it) where I was fighting in a war in a realm with lots of plant life in it, most of which are colored blue and green, and our commander is this blonde girl that I seem to know (to which, my friend told me that that girl was my Twin Flame). It felt as real as any other too.
As for these symbols, if they aren't really an AP experience, I'll try to search Akashic Records for it these if that might help, or even review these particular dreams from there.
Oh and by the way, about this "Retrieval", do you perhaps mean I am starting to recover/retrieve Past Life memories? And yes, as for challenging experiences, I did encounter a lot lately, one of those is the incident I summarized on my first post in this thread; hating myself (for the first time in my life) and all that mess.
And thanks for the article, I will read it once exams are over, too.
