It can take weeks to months to acquaint yourself to have one proper lucid experience - as in, you are completely aware, you are completely in control and you can keep your dream guardian at bay and enjoy the dreamscapes you create for as long as you want to.
I once experienced a lucid where I, Inception-style (this was back in 2007), lived my life doing different things at least I was 79 years old and died happily in my sleep next to my dog and then-gf. When I woke up I had only been asleep for two hours.
Lucids are also a bit on the dangerous side for people with any inherent dispositions towards addiction or loathing for life. You can become hooked away from reality and just drone on until you finally get back to where you have full control - the dreamscape.
