From the early 90's,  It was a duet I believe. I don't know the song title or singers but lyrics go a little like this:
                        (Guy singer)You're my dream girl....
                        (Girl singer) You're my dream boy....
  I'd appreciate any help, it's been driving me crazy for years, trying to find this song.
They played this at clubs and techno/house music stations.

I believe it's "Dreamboy/Dreamgirl" by Rockell and Collage(it's from Rockell's cd titled "What Are You Lookin' At?). Here are the lyrics:

I still remember the first time you said that you love me
you held me in your arms
and said you never ever leave me
(never ever leave)
to all these promises you kept
but it raised the past when I was well
you made my fantasies come true
my heart belongs to you
you're my dream boy
you show me you love me in every way
you're faithful to me every day
now i know that dreams come true
you're my dream boy
Collage:
My friends told me
that i was lucky
to have a girl like you
'cause all the girls i ever had
the love was never true
(love was never true)
you have brought me happiness
treasure the day when we first met
(oh yeah)
never ever gonna let you go
because i love you
You're my dream girl
you don't neglect me in anyway
you make me feel special everyday
now i know that dreams come true
Rockell:
You're my dream boy
you get me feel my heart with joy
and i can smile again
cause we found a love that would never end
Collage Rap:
You say that im your dream boy
that i fill your heart with joy
well you're my dream girl
you're all i want in this world
you give me the love i need
i know we're meant to be
talk to me...talk to me...talk to me...
Rockell Rap:
You hold me in your arms
i feel so safe and warm
when you look into my eyes
you have me hypnotized
you give me all your love
you're all im thinking' of
you made my dreams come true
my heart belongs to you
You're my dream boy
(You're my dream girl)
you show me you love me in everyway
you're faithful to me everyday
(everyday)
now i know that dreams come true
You're my dream boy
(You're my dream girl)
you don't neglect me in anyway
you make me feel special everyday
(everyday)
now i know that dreams come true
You're my dream boy
(You're my dream girl)
you show me you love me in everyway
you're faithful to me everyday
(everyday)
now i know that dreams come true
You're my dream boy
(You're my dream girl)
you don't neglect me in anyway
you make me feel special everyday
(everyday)
now i know that dreams come true
You're my dream boy
