Hey welcome to DV! I'm also from London ,which parts do you live in?

Being able to recall 4 dreams in one night is quite impressive and you are well on your way to becoming lucid if you keep this up. Out of the lucid dreamers I've met that had this level of dream recall from the start, had their first lucid dream in under two to three weeks. So just focus on recalling, and on achieving lucidity and it will happen.
