Serious answer, based on having taken some classes on dreaming: You may already have companions, but you may not yet recognize them. Characters for most dreamers can and do change appearance (sort of like a non-material version of the Doctor’s regenerations, though more like shapeshifters or illusions), but you can start to look for (or get a feel for) re-occurring characters or re-occurring spirits inside different-looking characters. Some people call returning benevolent ones “dream allies”.
As for developing your dreaming in general. First, try to get in the habit of recording them as much as you can, either on paper or to a recorder (there are apps for this). Second, try developing your awareness of your state both when you’re in the process of falling asleep, and when you’re dreaming but know you’re dreaming, and perhaps when you’re awake but the dream state is semi-available too.
