Drinking beer foam

I had a dream last night where I was drinking beer (specially the foam on top) from a plastic cup while I was lying on my bed. The cup was over flowing with beer foam. I am non alcoholic though. Does this have a meaning?

[H:O:R:A:C:E]

sure, there might easily be "meaning" to this dreamlet... but it lacks a full
context for me to draw any particular conclusions for you. who had supplied
you with the beverage?, what time of day was it?, where you anticipating
any activity to follow?... any such details might help to flesh out a storyline.

your posture was 'reclined and relaxed', and it was your bed, so we can
assume that you were particularly comfortable in this setting. the plastic cup
makes me think that this is a "casual" event... an everyday type of thing.
the overflowing cup reminds me of Psalm 23:5, which precedes:
"Surely goodness and loving kindness will follow me all the days of my life".
that you were supping only on the foam is suggesting that you've limited
yourself to the bare minimum of what's been made available to you.
the beer could be viewed as a form of 'spirits' (though undistilled), so it
could signify you drawing from a cup of spiritual wisdom.
