I have always loved to grow my gift in dream interpretation and am so humbled that the big man @nomad-magus has given us something to get the meaning of what the dream means. Let me reveal some of the hidden insights from that kind of dream.
First of all a swimming pool means a small number of people because of the water it contains as compared to the other large water masses, this is on a small scale and clearly show you are impacting something in the minds of people around you and this calls for you continous growth with in that realm.
Water in the swimming pool clearly represents revelation and this clearly seen in the scriptures
@Ezekiel 37, where water clearly starts as a small stream to a river where the water gets to your neck and instead you gat to just swim in it. This clearly means that you are growing in revelation and that is the sword of the Lord. As i said in some article where i interpreted a dream about that relationship related dream about some gal you desired but later found yourself with, now this clear that the girls represent female friend who want to have fellowship with you in the spiritual real and are desiring to be so close to you and that is why you see them swimming with you in the same pool. This is also known as partaking of the same doctrine that hold sacrosanct and that will enable them develop but in its is you moral authority to hold the right doctrine that's why you see a tattoo of black panther.
About you seeing yourself with a tattoo of black panther on your left hand is the clear sign that your are on the opposite side as for the doctrine you hold but that does not mean that you have lost it all. There are so many deep secrets from the movie Black panther and that is why you should take heed not be swayed away by the doctrine behind the black panther kind of thing which you captured in the spiritual realm.
Finally on the issue of you being naked, it clearly means that you are not having the garment or covering which we call the Grace of God and in this, it is a clear call for you to put on your garments according to the book of @Revelation 16:15, this clearly tells us that garments is the grace of God through Jesus Christ.
That is how i looked at it and perceived it according to biblical wisdom concerning dreams and their revelation in cases of such kind of prophetic dreams. Thanks @nomad- magus, it has been awesome to share something special with us who learn from you
