Hi @tasha89,
Tracy kindly shared a link to a collection of Astral Travels resources- that’s a great place to start! You could also browse the astral-travel tag for more resources.
For lucid dreaming, Celestia has some wonderful tips for you- I second the idea of making a habit! Do something over and over throughout your day and ask yourself if you are lucid dreaming- this builds the practice, as you will do it in your dreams too. I used to kickstart lucidity in dreams by looking for a clock 
You can find some more resources and experiences in the Lucid Dreaming discussion here:
Lucid Dreaming: How to Control Your Dreams
There’s also a dreams tag you could explore- although it contains posts about all types of dream magick.
Wishing you all the best- lucid dreaming and astral travel are both skills that take time and effort to build a successful practice, but they are both worth the dedication. I hope you can find some methods that work for you!
Good luck and blessed be
