Hi Michelle,
Whether in the spirit or in a dream, you may have visited an actual underground church. You were connected to what they were doing in the spirit and therefore were allowed to participate. Sounds like a very Holy Ghost service: singing, dancing, praying in tongues.
Hope this dream encouraged you that you are not alone and that there are many others like you who are hidden from view, but are still in love with Jesus and worshipping with freedom. “Worship Him in Spirit and in Truth.” Blessings to you, in Jesus name. Amen.
