So you drank cough syrup and had a slightly more vivid dream?
Well, 8 is the number of permanence, note how it is a tilted infinity sign. Tinted with the color red could mean
"Energy, passion, anger, inflammatory, lust, strength, protects against psychic attack. Mars rules red- Revenge, anger, pure sexual lust, and physical gratification, courage, determination, dealing with enemies. Red is used for inciting accidents, fires, and injuries. Red can also be used for self-confidence, athletics, strength, creating magickal energy for black magick, (Good for selfempowerment before workings of black magick) and inducing intensity. Incites lust, energy, strength, sexual energy, dynamism, passionate love, physical desire, courage, will power, athletics (especially competitive), and vitality. When used in black magick, red as opposed to black brings on sudden attacks, accidents, bloodshed, violence, and hatred. Red can also be used to incite wars, anarchy, and cruelty. Mars rules red. Red is of the element of fire. Both the colors red and black rule the root chakra."
So look that over and see if anything clicks. Jupiter is more correlated with purple then red, so i do not know. Dreams are highly personalized and it is intensely difficult for someone other then yourself to gleam any sort of useful information out of it. Ask yourself what it means to you, after doing just a hair of research on the many facets of the dream, and that answer that you come about yourself will be infinitely more helpful then mine.
Secondarily speaking, could have just been a trippy cough syrup induced dream that doesn't mean anything. In my experience, you can tell when something ~magical~ is happening. Trust your intuition, if it says that this is nothing, its likely nothings, and vice versa.
