SOmething weird is going on. Some years ago when i used to practice dream journaling( which is stopped after few months) i discovered i could say mantras of what i want to dream about and it would happen. Lots of times in fact.
In my case it was "I want to dream about girls".

Now that i started to journal again and dream recall, i also do mantras about what i want to dream about( yeah girls again) and now i don't really . Only one time i got my mind to listen and i got a girl in my dream.

But seems now my mind doesn't listen.
It's not even remembering dreams that well. I wake up like 4 times per night with alarms..but actually i even wake up bymyself without alarms(before the alarms) and i just don't remember nothing. So i may be dreaming about girls but i dont know.

But anyways, it seems my dream incubation is not working.

This is what i do to try to dream of what i want:
-In day time, repeat several times "I want to dream about____"
or "In my dream I meet ____"

I do this with eyes opened or while meditating with eyes closed.

-In night time when i close my eyes to sleep do the same thing repeating over and over and imagining images of whatever i want to dream about.

*****
But it just doesn't work. Could it be because i'm older now?
NOw i'm in my 30s. And i think back when i tried dream journaling before i was 20 something or 30

Or am i doing something wrong?
Before i easily had recall and also had what i wanted to dream about in my dreams tons of times.
