I don't understand anythinggg

So, I've been having OBEs for a long time. But the problem is, is just the OBE. I can't see anything but white. I can stand up, I can move, but I can't travel, my thoughts are only my thought, etc. It's nothing like the experiences I read. Sometimes I open my eyes and I do see "my bedroom", and in the best case I can open my eyes in another place, usually related to the sea, for 2 seconds, and then again I am here and everything is white again. I got to the point where I tried to walk without seeing anything and I hit my little finger against something on the floor. Some people have told me to try saying things like “vision”, “let there be light”. And I have, but they don't work.

Also, In astral projections you can spend a lot of time and here it is not so much? And then that the experience had coherence and everything. Are there people who do it?
