Hi everyone!

Can you please confirm the accuracy of:

Ná stop ag brionglóid riamh! = Never stop dreaming!

Thank you

I can’t.
brionglóid is a noun (a/the dream). It is not a verb (I dream) or verbal noun (dreaming).

Ná héirigh as brionglóid a dhéanamh riamh

or: ... brionglóid a bheith agat

I understand. Thank you for your help!

Hi again

Is there another word for “a dream” instead of brionglóid?

As in a dream, not a vision, premonition or sleep etc.

Also, is there a way to say “a dream within a dream”?

Thank you!!

yes, there is: taibhreamh (as brionglóid means "uneasy thoughts" in Munster Irish, anyway). Pronounced TY-rev. You can hear the exact pronunciation at https://www.teanglann.ie/ga/fuaim/taibhreamh

Taibhreamh istigh i dtaibhreamh?

May you always have dreams: go ndeintear taibhrithe i gcónaí dhuit! (or "go ndeintar")

Go rabhais ag síor-thaibhreamh!

Ná bí aon lá ná aon oíche ded shaol gan taibhrithe a dhéanamh duit!

Thank you so much for the detailed reply!! : )

Maybe this should be: gan taibhrithe á ndéanamh duit. I think Labhrás would know the answer.
