do they exist? i read a book by robert moss i believe, on them.
and have you ever come across a gate you couldnt pass/go through?
yes, I have. A portal it was. Richie (aka Timeless) travels through portals a lot in his lucid dreams. I have seen them on occasions, and only one time I dared to go through, I was assisted by two people who held me while we went through. It was marvellous, I ended up in the universe 
(maybe some day this dream will be in my DJ 
)
edit: oops I misread, you want to know about gates you couldn’t go through…
well, what would those gates look like? I can recall a dream now where someone told me I wasn’t allowed through a certain door and I complied. Is that what you mean?
yes exactly!!!
the only gates I have come across in my dreams are more like fences, or chain link-gates with a locked door… they usually split and block off areas of my dreams… I usually look for a gate-keeper and see if they will open the gate, and if i cannot i will usually phase through it…
but if I were ever advised not to pass through a gate i would listen…
We have a topic on this already somewhere, I remember posting in it a few years ago. Checkout the archives when you have some free time, I’m sure it is in there somewhere.
have tried to make portals and they usually don’t work right
have not really found portals, but have found transportation to new dreams
one of my first full length LDs I was wandering in an alley around these trash - cans and was transported to a mystical fractal rainbow wonder-land of so much effervescent beauty that i fell to the ground weeping thanking God!
now, I lost my keys apparently, how do I get back? How do you do that? Where was it? Hmmm. 'Twas many years ago. Between 13-16… probably 13.
usually if i am very very lucid for quite a while I will encounter walls that I cannot pass through which then turn to 3-dimensional blackness which i can touch and push and fumble around in, which eventually take me to new dreams, or to waking up, depending on depth of lucidity and will-power.
From the 3d-void I can create new dreams, sometimes I get there by going through a wall, and one time saw DCs LITERALLY walking through a wall and followed them, and they told me “to dream travel just go through a wall and think of who you want to meet.”
and had 3 random women who looked like witches come and take me to a lucid dream society one which was real cool but they put me in jail for fighting even though i was defending myself!
these could be “portals” ?
