First, is this possible? The short answer is yes of course it is possible to lucid dream in one night. Sadly the long answer is different and you read here why the long answer is different from the short answer.
What does it take to lucid dream?
There are multiple ways of lucid dreaming ways and methods. Basically, the most known one is the person who gets a lucid dream occasionally, and there is the one who never gets a lucid dream. For the people who already have had experience with lucid dreaming getting lucid takes less effort. For people who are completely new, it takes more effort to become lucid. This means that getting lucid in one night suddenly becomes a lot harder.
Getting lucid a lot takes dedication and time, if you are learning Mnemonic Induction of Lucid Dreams (MILD) it can take some time before your brain realize that you are trying to lucid dream. Of course, this can be completely different per person, but from my 3 years of experience as owner of Night Realm, I have learned it takes between 1 and 2 months before they find any results with MILD.
You can increase the chance of getting lucid with a Wake back to bed. This is a method where you wake up from the middle of the night and doing your MILD technique or Wake induced lucid dream technique. In the end, you see it takes a lot of effort to become lucid, and I haven’t even started about dream journaling and reality checks.
How do I get lucid tonight?
For the people that still want to try to get lucid tonight and you still got the whole day this is how.
First, you start getting an intention going. Intention is a way to set your mind towards your goal. Your goal is getting lucid so you tell your brain “I want to get lucid” multiple times during the day.
The second step I would suggest you doing is trying to get used to doing a reality check. If you have a reality check you can recognize a dream from within a dream. Outside doing that you will get more aware during the dream.
Now it is almost bedtime ready to become lucid. Your goal is to get the most out of your night. So I recommend you have time to sleep for at least 8 to 10 hours. Within this timeframe, I recommend starting your bedtime by setting your alarm for a Wake Back to Bed. This alarm should be 4 to 6 hours from your bedtime. There are alarm ways to put you directly in REM (Rapid Eye Movement) sleep but this is not recommended doing when it is your first night.
After you set your alarm you need to do your reality check for the last time, and probably a couple of times your Intention, after you did this I recommend doing a small meditation session. Meditation can help you be more aware in dreams and fall asleep a lot quicker. My recommendation is to meditate for 10 to 15 minutes with mindfulness meditation. Mindfulness meditation is when you lay on your back and just be aware of your breathing and try to make your thoughts fly by (basically do not interact with your thoughts).
If you follow this you have a chance to become lucid!
Yes, it is possible to get lucid tonight but you will see that it takes a lot of effort during the day to force this. I haven’t talked about the most important stuff you should do as a lucid dreamer like a dream journal. This Is really important to become more consistent and that you remember more from your dreams. I would suggest you follow a complete guide on Mnemonic Induction of Lucid Dreams if you are still interested in becoming more lucid and learn more about the wonderful world of lucid dreaming.
