There are times when we sleep amazingly well with great dreams, and times when we sleep horribly, have terrible nightmares, or can’t sleep a wink. Let's review what can impact your sleep astrologically!

Transits impacting sleep:
Sleep usually comes under the domain on Neptune, the 12th house, and Pisces. You tend to have a hard time sleeping when you have a hard aspect - conjunction, square, or opposition - by the Moon, Mars, Saturn, Uranus, Neptune, or Pluto to the 12th house cusp, 12th house ruler, or natal Neptune.
With the Moon it usually needs to be a hard aspect that goes exact during the period you’ll be sleeping (because Moon aspects only last about 4 hours, so if it’s during the time you should be awake, it won’t impact your ability to sleep).
Hard Moon aspects usually show some sort of emotional reason for not being able to sleep, perhaps being worried about something, or excited about something, or upset about something. You can also be more prone to nightmares with hard Moon aspects during the period you’re sleeping.
Hard Mars can bring too much energy for you to sleep, and you can feel like you’re going nonstop and have a hard time unwinding. When you see a hard Mars aspect (and actually, with hard Mars, this can apply to your Sun, Moon, or Mercury as well, if they don’t rule the 12th house), you usually need to be physically active so you can use up the energy and exhaust yourself physically.
Hard Saturn aspects can just wipe away sleep completely, and you try to get sleep, but just toss and turn, yet you feel exhausted. Saturn is the punisher if you’re not doing things the right way, so often, if you create a good sleep routine and stick to it, you can get your sleep back. That means practicing good sleep habits and keeping up with them.
Hard Uranus aspects can make sleep come-and-go. You can sleep some nights and not get a wink other nights. This one’s a little harder to manage, and you need to just take advantage of the times you do get sleep and get as much rest as you can so you don’t burnout at the worst moments. You can also have wacky dreams with hard Uranus - just get used to those and maybe invest in a dream dictionary!
Hard Pluto aspects can be the worst because they last for up to 3 years, and are notorious for bringing bouts of insomnia (and this can also apply to hard Pluto to your natal Sun, Moon, or Mercury).
Pluto always wants deep changes, but they may run deeper than just simple changing of sleeping habits, and it’s likely that whatever is causing the insomnia is actually tied to a deep emotional issue that needs to be worked on, or stress that’s from some part of your life that’s impacting your ability to sleep.
Hard Neptune aspects can also impact your sleep, and they can be hard aspects to any of your natal planets, though the biggest impact will be on your natal Sun, Moon, Mercury, Mars, or ruler of the 1st house. You may find that you’re constantly exhausted and lethargic, but when you try to sleep, you just can’t, or you have bad dreams.
Your dreams can become much more lucid with all Neptune aspects since your subconscious mind is trying to come out to play, so try paying more attention to your dreams and see what possible messages they may have for you that you need to listen to. This can help to mitigate the bad sleep.
Good periods for sleep can come with sextiles and trines to your 12th house cusp, ruler, or Neptune; the Sun, Moon, Venus, or Jupiter in the 12th house; or positive aspects by Neptune to your chart.
