PLEASE help me re-create this awesome effect...or just read...

So ok, i need to tell you my story.
My beginnings with lucid dreaming -
few years ago.
But i tried few times and failed.I even didnt knew what it is WILD.
My knowledge was almost 0.
I only knew that when you will awake in your dream and ask yourself if this is a dream - you will have controlled dream only limited by your imagination.
And i leaved it.

Few months ago i started to learn speed reading.
I concentrated mostly on eliminating subvocalization.
And i concentrated on that thing so hard that i created strange feeling inside my head.
Like some pressure inside my nose region but more inside head.
Maybe somewhere in amygdala region i dont know.
This feeling was like some vacuum or trance feeling, i really dont know how to describe it.

Later that day at about 11.00 p.m i went to sleep, to bed.
And then - this was awesome:
I realized that i am on some swimming pool.
NAKED.
And i gained control and asked myself - how possible is that ?
And i remembered that in ld i should check a watch.
I checked and this watch has like 3 hands...
And i realized that i am dreaming.
And shock.
And i woke up.
In fear.
But i told to myself - now i will try smth - and using this feeling in my head, i remembered it and created again (this feeling when i was learning to eliminate subvocalization) - using this feeling i returned to my dream but i was again so shocked that i told to myself WAKE UP. And i woke up.
and i did it again.
And i touched myslef to see how real is that and i tried to scream and i woke up again.
And in summary this was like 4 times - in and out, later i fall asleep and i had normal dream.
From those time i can not recreate it.
How to do that again ?

Do you remember what time of night this happened? Aim for the same time period, and try to use your head-pressure trick to WILD. Maybe it helps you focus, or squelch your thoughts, or something.
