Thank you for sharing your dream with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
Pray to cancel any such dreams upon waking. Pray for mercy and deliverance from previous and current addictions if applicable. Do your part to close any open door ways (watch you, read, hear) that makes you yield into temptation. Sometimes, such dreams can be demonic attacks including witchcraft. Finally, check your environment and the partners that you have.
You need to be secure in who you are Christ if you have truly given your Life to Christ and He is your Lord and Saviour. The enemy always roams around like a roaring lion looking for who to devour (1 Peter 5:8). If you are innocent of partaking of any sinful thing, resist the devil as per James 4:7 and never forget the true meaning of the Armour of God (Ephesians 6:10-18) and put it on regularly. Do not neglect spending time with the Lord regularly be it through reading the Bible, praise and worship. This spiritual discipline part of your life is critical.
