Wow @MagpieMoss it sounds like you have a vibrant and abundant inner world 
Thank you for sharing those.
I’m definitely no expert on dreams but I have, in another life, spent time talking with a sleep scientist, psychologists and occultists talking about dreams and one thing which came out of those converstaions - which I hope may be a reassurance - is that we all dream, every night, several times a night. So even though the weed may inhibit the remembering come morning, those dreams are still happening.
In terms of accessing and developing dreams, I have found that the more I practice awareness before I go to sleep and note taking when I wake up, the more vivid the connection and recollections become. So, at night in bed I might ask an oracle what i should look for in dreams or, conversely, if there’s something i’m struggling with in the waking world - i may chose a card, rune, or some other totem to represnt the problem and ask that my dreams help me explore solutions. I may just say to myself, as i’m falling asleep, I’m going to the dream place now, what will i find? Who will I meet? What objects can I bring back?
Because I have some health issues, I cannot journal the way I used to but I do occassionally use a voice-to-text app to record what I remember, even if it’s just impressions or a phrase of words.
In terms of astral projection, there is a wonderful free course called Quaeria by Josephine McCarthy which hwlps with this Quareia
One thing I would mention about astral projection is, for some folk this may not be as accessible or possible if they experience Aphantasia (an inability to form mental images or strong mental images). I have this (related to early CPTSD) and it’s caused a lot of shame in certain circles and programmes of learning which rely on mental images but I believe there are other ways and means, too.
I hope your journeys are full of magick and connection.
Blessed be.
