A sense of urgency

I had a lucid dream last night, which i immediately knew was not going to last very long. I was lucid since i started dreaming, and instantly felt a sense of urgency. I did not even take the time to question why i should be in a hurry, i just immediately acted upon the lucid goal i had assigned myself before i went to bed.

I was in a car parked next to a house. My cousin and sister went inside and told me to stay in the car and i knew i was dreaming. I immediately went inside and told them both that i need them to hurry and take me to my dream guide. My cousin said nothing and immediately took my hand an took me down a hallway into a room and faced me towards a closed closet. I went to open the closet, and my alarm woke me.

I have experienced this many times before: feeling like my dream is going to end soon, and it always does. Has anyone else experienced this kind of sixth sense while lucid?

Most often its my alarm that ends the dream, which could explained by a sort of unconscious sense of time which seems very plausible...
However i have also been lucid, felt that my dream was going to end soon, and been awoken by things like slamming doors, or my bird squawking really loud.

Yea it is quite interesting how our bodies get accustomed to something we set it to do -- whether it's knowing when our alarm clock will go off, or remembering a goal inside the dream. We do have a body clock, which helps us get up at roughly the same time and go to bed at roughly the same time. If you set your alarm at the around the same time a lot, your body will get used to this and start expecting it.

I think we also don't fully comprehend how much the little things that happen in waking life can send signals to our brain and subconscious, and affect us in the dream. There is also dream incorporation where sounds, etc in waking life get incorporated into the dream while they're happening. Doesn't that make you think..

What if you unknowingly heard every microsecond of the sound of a door closing in the real world, and god knows how fast our brain interprets those signals and create scenarios and possible outcomes, so we end up waking up right before it slams. Kinda like our body being hyper aware of the surroundings. I mean after all, it has a scientific use -- which is for survival and to be conscious (though not fully) of our environment.

Finally, I suggest that when you get lucid and get that feeling that your dream is gonna end, think about something else! Occupy yourself with something else to do, perhaps a task or some other thoughts. Because once you think something, your mind would revolve around that and make it happen. After all, dreams are all made of thoughts, they are fueled by your thoughts. So any small thought about your dream ending will indeed make it do so.

:) congrats on the lucid dream by the way!
