Let me tell you what the dream means. At the time of your dream, you were somewhat involved with a ministry or project (airplane), but not really on board (leaning against, outside). The ministry took off (airplane takeoff) and you held on to the fringe (outside the plane). Then you learned something spiritual -or became more spiritually minded as a result (landed on mars/ "the heavens").
The Bible has a lot to say about dreams:
Bible dreams:
1. God admonishes (Genesis 20:3-7, Daniel 4:4-33).
2. God reveals a connection between heaven and earth (Genesis 28:10-16).
3. God instructs (Genesis 31:10-13, 46:2-4, Job 33:15-16, Acts 18:9-10).
4. God warns (Genesis 31:24).
5. God foretells success (Genesis 37:5-8).
6. God foretells Benjamin’s birth and Joseph’s exaltation (Genesis 27:9-11).
7. God provides the interpretation (Genesis 40:5-13).
8. God foretells disaster (Genesis 40:16-19).
9. God foretells a social crisis (Genesis 41:1-32).
10. God speaks to prophets in dreams (Numbers 12:6, Jeremiah 23:28 & 30:1-26).
11. God speaks to sinners in dreams and seals their fate (Judges 7:13-15).
12. God doesn’t give dreams when there’s disobedience (1 Samuel 28:6, Micah 3:5-7).
13. God questions the soul in dreams (1 Kings 3:5-15).
14. God bests dream interpretations (Daniel 2:27-28 & 31-46) by revealing another’s undisclosed dream (Daniel 2:1-5 & 19).
Other facts about dreams:
1. God is the source of dreams (Joel 2:28 & Acts 2:17).
2. Dream interpretation is God’s gift (Daniel 1:17) and God’s written word judges gifts.
3. Dreams reveals the mind of God’s on matters and it may not be pleasant (Job 7:14).
4. Unbelievers will try to discourage and attack God given dreams (Genesis 37:17-20).
5. The Bible also uses the term night visions for dreams (Job 4:12-13).
Opinions are just that, opinions. God's word provides the best answer for every questions people face today (2 Timothy 3:16). A simple study on the word "dream" reveals a lot.
