Nice one endlessness...
Very cool for you to take this initiative.
My more extensive advice:>
Before hand...
(Living well, and resolving any issues that might be heavy on you are always decent starts, but often we go to Hyperspace for help with our problems, so my advice here is more along the lines of: )
1) Meditate - Clear your mind and evict any obnoxious inner voices or negative emotions.
2) Make sure you have enough vitamins and water in your system. (B Vitamins, C, choline, 5-htp or whatever you need)
3) Create a clear intention to carry with you into Hyperspace (short and sweet).
4) Play music that makes you feel safe and loved in the background.
5) Clear your space. (Not necessarily cleaning the area, but with your intent, incense, reiki if you know how. A bit of Feng Shui never hurts.)
During...
1) Have a handy mantra to fall back on. (Doesn't have to be esoteric, but can be as simple as All Is Well or the like.)
2) Stay calm and banish any negative emotions as or before they arise. (Fear & Anger attract the baddies IME)
3) Actively use your intention to go and find the experience you want. (Nothing wrong with being passive and seeing what comes, but if you are not happy with what is going on... move on to something better. This may take a bit of practice, but it is not unlike navigating a lucid dream.)
4) Try not to focus on, pay attention to, give energy to, or otherwise encourage any beings or spaces you might encounter that resonate with anything that doesn't seem wholesome, uplifting, and loving to you. When in doubt, seek something higher and lighty-er.
(There is no shame in avoiding a potentially troubling encounter, or even calmly fleeing from a situation that simply feels wrong to you.)
If you are cornered and accosted, and can not avoid an encounter...
1) Command the entities to leave your presence. (takes confidence, and can be impossible if they were drawn to your fear in the first place...)
2) Use your mantra, or an Icaro (song or tone).
3) Ring a bell. If you have a Tibetan tuned bell or bowl, these can be great.
4) Shake a shaman's rattle.
5) Dance.
6) If all else fails, you can call on guardians you have met previously or have affinity for. Allies that might come to your aid can take any form, and the spirit of the vine itself can be quite protective. It helps for this if you have cultivated friendships and have worked with your guardians previously, but you might be surprised who will come to your aid if you implore with sincerity.
7) In the end, the last resort (and also most effective) is to call upon the Universal power of light and oneness. Whatever your spiritual belief system, this power is your birthright as a child of the Omniverse. Admit that you have reached the limit of your ability to protect yourself, and call upon the highest power you can envision... the light that will radiate through you will be able to dispel any darkness. Remember to be humble if you do this, as it is not your personal power that you have channeled or called upon.
After...
1) Write down your experience in a journal.
2) Think deeply about what happened, and try to remember events that might have slipped your mind.
3) Fill in blanks in your memory patiently.
4) Talk your experience through with someone who would understand and can ask you questions you might not remember to ask yourself.
5) Meditate on the most impressive or important aspects of your experience. Contemplate symbols and images.
6) Be thankful.
7) Let it all go.
Disclaimer: If portions of what I suggest here run counter to your belief system or conceptions of reality... ignore them.
There is quite a bit more to say on this, but I will leave it at this for now. I need to go and get some grub.
A little sage burning never hurt anything.
